Nvidia driver, CUDA tools and libraries

nvidia-logo-1

Oh no, another Nvidia driver repository? Why? This repository reflects my personal view for the way the driver should be packaged for Fedora and CentOS/RHEL. It’s somewhat different from ELRepo repositories for RHEL/CentOS and from RPMFusion packages for Fedora.

Repository installation

To install the repository on a supported Fedora distribution, run as root the following command:

dnf config-manager --add-repo=https://negativo17.org/repos/fedora-nvidia.repo

To install the repository on CentOS/RHEL:

yum-config-manager --add-repo=https://negativo17.org/repos/epel-nvidia.repo

The Nvidia software packages are available for installation by default also in Gnome Software.

Please note that the driver will show up only if your system matches one of the PCI ID supported by the driver. Otherwise, only the other Nvidia programs (mostly for CUDA development) will show up in the software center.

What’s different?

First of all the packaging is a lot simplified; more stuff is compiled from source, smaller packages and more options. This packages try to comply as maximum to the Fedora Packaging Guidelines; which means they have debuginfo packages, default Fedora’s GCC compile time options (where possible) and standard locations for binaries, data and docs.

What follows below, is a detailed explanation of all the “differences” from the various Nvidia driver packages that I was able to spot on the web and a detailed description on how to install components, etc.

Nvidia drivers

Packaging

  • nvidia-settings, nvidia-persistenced, nvidia-xconfig and nvidia-modprobe are compiled from source.
  • All RPM filters except for GL and OpenCL libraries have been removed, so there is no weird dependency option in the SPEC file. RPM pulls in all correct requirements on its own. This is to avoid pulling in the Nvidia drivers instead of the Mesa libraries or in place of the new open source OpenCL support that’s in Fedora.
  • Simplified packaging with much simpler and readable SPEC file.
  • Dependency on libva-vdpau-driver. So in Totem, or any other libVA supported application you can benefit from VDPAU acceleration.
  • Sources are generated with a script and inserted individually in the various packages; so it can be easily reproduced just by changing the version and rerunning the script.
  • nvidia-xconfig is not required on anything that uses the modular X.org directives, as it writes too much in the configuration file (keyboards, monitors, etc.) and the required entries should be written in separate configuration files under /etc/X11/xorg.conf.d. The package is still available as it’s required to speed up some configuration like multi-monitor setups with SLI Mosaic enabled from the command line, but not installed by default.
  • The NVIDIA OpenGL-based Framebuffer Capture (NvFBCOpenGL) libraries (NvFBC and NvIFR) are private APIs that are only available to NVIDIA approved partners for use in remote graphics scenarios (i.e. Steam In-Home Streaming hardware encoding); so they are packaged in another small package called nvidia-driver-NvFBCOpenGL.
  • The nvidia-settings package now builds the external libXNVCtrl.so library that can be used to control the graphic cards through the NV-CONTROL extension. This library updates the old and obsolete one in Fedora.
  • The nvidia-settings binary is compiled with GTK3 instead of GTK2 on Fedora and RHEL/CentOS 7+.
  • The driver can be installed separately from the nvidia-settings utility, so if you simply want a working driver and do not care about details, your experience should be as close as possible to the one with open source drivers.

Versioning

  • ELRepo ships 32 bit compatibility libraries in a separate package with x86_64 as the architecture and “32bit” in the name. 32 bit libraries should be like in RPMFusion, with an i686 package installable in parallel with the x86_64 one. There are no other packages in the distribution that are built for x86_64, with “32bit” in their name that contain i686 binaries (!), so Nvidia drivers should not be an exception. So no separate “32bit.x86_64” package for 32 bit libraries also on CentOS/RHEL; just install nvidia-driver-libs.i686.
  • Versions are not hidden; all packages have the same driver version.
  • No alternatives system, only the latest version which integrates CUDA support is available. For older releases nouveau works great; and anything below a GeForce 8xxx it’s in my opinion too low end to play anything modern. And Quake 3 and Doom 3 work greatly with nouveau, so that’s not a case!
  • The CentOS/RHEL repository contains the “Long Lived Branch version” where less changes occur; while Fedora repositories contains the “Short Lived Branch version”. Beta CentOS/RHEL and Fedora’s rawhide repositories will contain the “Beta Branch version”

CUDA support

  • CUDA libraries/tools for the driver are split into subpackages. There’s no need to install all the CUDA libraries and tools on a system that has only one adapter and is used for occasional gaming or for simple office use. This can save ~120 MB worth of installed libraries. nvidia-persistenced falls in this category as it’s not needed on a normal laptop or gaming system.
  • Complete packaged CUDA stack has been added for all supported distributions, all the packages provide/require/obsolete the relevant packages in the Nvidia CUDA repository; so you can enable this repository along with the official Nvidia CUDA one (x86_64 systems only).

Kernel modules

  • Multiple choice of kernel module packages; akmod (RPMFusion) for Fedora and binary kmod (Kernel ABI whitelists) for CentOS/RHEL. In addition to this, on both distributions dkms packages are available. This way all cases and personal preferences are covered for both distributions.
  • The Nvidia udev rules leverage nvidia-modprobe command in the system to create devices and set permissions even when the userspace libraries have not been loaded yet, covering the case of Wayland only sessions and compute only system without display userspace components installed.
  • The nvidia-uvm module has a soft dependency on the nvidia module, making sure that these modules are not included in the initrd (thing that would happen by using systemd’s configuration (module-s-load.d). UDev rules make sure the module has proper permissions.
  • Choice of proprietary or open source license kernel modules.

Default configuration

  • Dracut options are depending on the distribution; so no more “vga=normal is an obsolete option” at boot. Each distribution gets its own specific GRUB options for booting.
  • 96 DPI is written in the default xorg.conf config file. Why? Gnome 3 by defaults hard-codes a 96×96 DPI resolution, most of the free drivers do (intel, nouveau, etc.) as the EDID is almost never reliable (please see the excellent Adam’s Jackson post where he explains this). As an example, if you install the Nvidia drivers on a RHEL/CentOS 6 laptop where you used to have nouveau installed (96 DPI hardcoded), the fonts gets 90% of the time supersize and ugly as Gnome 2 and the Nvidia driver do not hard-code 96 DPI like Gnome 3.
  • Make X.org NVIDIA Files section to be loaded latest in case there are other packages providing a custom Files section.
  • Use new OutputClass directive on X.org server 1.16 (and later) to load the driver and do not rely on an edited /etc/X11/xorg.conf file. This also removes editing of the xorg.conf file from the package scriptlets. This does not hardcode the 96 DPI resolution.
  • Add the IgnoreABI directive by default on Fedora rawhide builds.

Kernel modesetting and Wayland support

Kernel mode setting on the nvidia-drm module is enabled by default along with the console frame buffer driver.

Distribution and Nvidia driver version support

Here is a rundown of Nvidia supported drivers and options split by distribution. Basically, CentOS/RHEL will always get a Long Lived branch release if possible, Fedora always a Short Lived branch release, and unreleased distributions will always get a Beta driver.

Optimus laptops

The driver should install and operate cleanly whether you are installing it on a system which has one or more discrete Nvidia cards or an Optimus laptop with an Intel and a Nvidia card. Nothing to do to enable or configure Optimus.

This is up to the point that when the drivers are installed, you can even turn off Optimus on or off in your system Bios (if your laptop allows that) and the only difference you should see is that there’s an additional VGA card enabled in your system (check with lspci) and that the Nvidia control panel switches between a PRIME Display, like in this picture:

And a normal RandR managed one, like in this one:

Everything else should not be different from your normal experience.

Limitations with the Nvidia driver

The limitations are the same as provided by the Nvidia driver, this means that if you are running it on an Optimus laptop, the Intel card can never power off. Which means higher power consumption, unfortunately. If you have an Optimus laptop and absolutely need the proprietary drivers, my suggestion is still to disable Optimus in the Bios.

Limitations with the OSS stack

On the contrary, if you use the OSS stack (nouveau/intel) the second card can be powered off if there’s no application running on it or display directly connected to one of the card’s outputs. That’s the best reason to use the OSS drivers at all if you you’re not doing serious gaming or 3D work:

$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynOff:0000:01:00.0

You also got the nifty selection menu about running your game on the discrete card on Gnome, which is really cool:

It will power up the video card just before launching the process. Launching a program through that menu entry is like starting it from the command line with the DRI_PRIME variable declared. For example, the same as above would be:

$ DRI_PRIME=1 quake3 &
$ sudo cat /sys/kernel/debug/vgaswitcheroo/switch
0:IGD:+:Pwr:0000:00:02.0
1:DIS: :DynPwr:0000:01:00.0

As you can see, the discrete video card is turned on. For Steam, you still need to edit each of your game to run on the Nvidia card:

SLI systems

SLI is now enabled by default with the Auto profile, there’s nothing to do if you have a SLI system. If you need any different SLI option (AA, SFR, etc.), just override it in X.org configuration files.

Nouveau fallback

With the new expanded OutputClass support for X, as carried out by Hans, it’s now super easy to switch to the OSS stack if the proprietary Nvidia driver somehow does not work. No user space component is touched, as soon as the Nvidia kernel module is not loaded (check on /sys/module/nvidia), the desktop starts with the normal OSS components you get with a normal installation. Thanks to all the work done on libglvnd, the libraries loaded are the correct one for the driver you are running.

This means that the performance of the Nvidia card would be abysmal, but still you would get a nice desktop and browser to Google around for answers on how to fix it :).

Sample installation

Here is an example. Let’s assume you have a freshly installed CentOS system with a recent Nvidia GPU and you want to:

  • Install the driver for gaming
  • Play Vulkan enabled games
  • Want to be comfortable with the Nvidia control panel
  • Play 32 bit games (Vulkan included) on a 64 bit system
  • Play 32 bit Vulkan games on a 64 bit system

Is this ok [y/N]:

As you can see, this system has akmod enabled kernel modules and libraries for running 32 bit applications. The amount of data to download for the drivers is really small compared to packages that contain CUDA libraries and tools.

Package installation

If you are booting the system in UEFI mode; as a prerequisite to installing any external module (not built into the kernel package), you have to disable UEFI Secure Boot in the system configuration. All modules contained in the kernel package are signed with keys that are generated during build and deleted when packaging. If you want to preserve Secure Boot, you need to sign the modules yourself and import the keys into your hardware module. Doing so is out of scope here; if you need a decent guide just follow Red Hat’s guide for signing kernel modules.

First of all remove all the Nvidia drivers you might have on your system due to RPMFusion, ELRepo, or the Nvidia CUDA repository. This is usually accomplished with the following root command:

yum -y remove *nvidia*

Then, to install the Nvidia driver and its control panel utility in CentOS/RHEL with the binary kABI (Kernel ABI whitelist) module (this is the default on CentOS/RHEL), perform the following command:

yum -y install nvidia-driver nvidia-settings

To do the same in Fedora, using akmod modules, perform the following command:

dnf -y install nvidia-driver nvidia-settings

Specific driver installations

For both Fedora and CentOS/RHEL distributions it’s possible to install additional packages and / or variant of the basic kernel modules. This paragraph contains some examples. Make sure you have the EPEL repository enabled if you plan to use DKMS modules on CentOS/RHEL.

akmod kernel module variant (Fedora):

dnf -y install nvidia-driver akmod-nvidia

DKMS kernel module variant (Fedora/CentOS/RHEL):

yum/dnf -y install nvidia-driver dkms-nvidia

To add 32 bit libraries on a 64 bit system (for games or applications like Steam):

yum/dnf -y install nvidia-driver-libs.i686

Proprietary and open source kernel modules

Since almost a year, the Nvidia driver ships with two different implementations of the kernel modules, one proprietary and one open source. The open source one as of drivers 545.x is now considered beta quality also for the workstations, so it seems a good moment to start shipping it.

The open source one is supposed to be the only one that will be kept in the future, but at the moment both are available and both differ in terms of functionality. You can read about the main differences in terms of functionality and what chips they support in the official documentation.

I did not want to introduce another variation of the kernel modules beside akmods, kABI and DKMS, this would have created even more confusion and lots of dependencies in the SPEC files for the variations. The new akmod and DKMS packages ship both sources (MIT/GPL and proprietary kernel modules) and allow you to switch between one or the other through a configuration file.

Considering that in the long run only the open source variant will remain, I wanted to make this as transparent as possible for the users. Basically, if you don’t care and just want something that works, nothing has changed for you.

The two sources get referenced as they are referenced inside the Nvidia run file, namely “kernel” for the original proprietary kernel modules and “kernel-open” for the new open source variation.

The following instructions show you how to switch between one implementation or the other.

DKMS

Check which version you have installed:

# modinfo -l nvidia
NVIDIA

Change the type of modules you want to use and trigger a rebuild and a reinstall:

# sed -i -e 's/kernel$/kernel-open/g' /etc/nvidia/kernel.conf
# dkms build -m nvidia/545.29.02 --force
# dkms install -m nvidia/545.29.02 --force

Now check again the license and you should see that it has changed to MIT/GPL:

# modinfo -l nvidia
Dual MIT/GPL
# reboot

To switch back, change the configuration again and then trigger the same process for rebuilding installing:

# sed -i -e 's/kernel-open$/kernel/g' /etc/nvidia/kernel.conf
# dkms build -m nvidia/545.29.02 --force
# dkms install -m nvidia/545.29.02 --force
# reboot

akmods

Check which version you have installed:

# modinfo -l nvidia
NVIDIA

Change the type of modules you want to use and trigger a rebuild and a reinstall:

# sed -i -e 's/kernel$/kernel-open/g' /etc/nvidia/kernel.conf
# akmods --rebuild

Now check again the license and you should see that it has changed to MIT/GPL:

# modinfo -l nvidia
Dual MIT/GPL
# reboot

To switch back, change the configuration again and then trigger the same process for rebuilding installing:

# sed -i -e 's/kernel-open$/kernel/g' /etc/nvidia/kernel.conf
# akmods --rebuild
# reboot

Additional driver configuration to your system

To add additional configuration to your system, just create the /etc/X11/xorg.conf file. For example:

Section "Device"
Identifier "Device0"
Driver "nvidia"
Option "NoLogo" "true"
Option "DPI" "96 x 96"
Option "SLI" "Auto"
Option "nvidiaXineramaInfoOrder" "DFP-0"
Option "metamodes" "GPU-a493fbbb-7d76-86a2-8764-d76d487a75a7.DVI-I-1: nvidia-auto-select +0+0, GPU-c02960a4-be28-d5ce-8b02-be04b5e2550b.DVI-I-1: nvidia-auto-select +1680+0"
Option "BaseMosaic" "on"
EndSection

In this example we have 2 video cards with one monitor each, so we enabled SLI, Base Mosaic to have multi monitor support on SLI and make a layout with the second GPU monitor on the right of the first one. Also, we fix the DPI to 96×96, which is the hardcoded default in Gnome and in Open Source drivers.

Configuration for CUDA only systems

Your system might only be used for CUDA development and not require the X server to be running the DDX driver at all, so you might want to tweak the configuration a bit to make the system load (for example) the Intel driver as the main display and just the Nvidia driver for GPU workloads. In this case you have two options.

Option with only CUDA components installed

To install just the CUDA components of the driver and not the OpenGL libraries and all files required by the DDX part of the driver, proceed to install as follows:

# yum install nvidia-driver-cuda

Is this ok [y/N]:

As you can see, there are no components providing OpenGL or DDX drivers installed on the system. This will not use any X (or Wayland) configuration compared to what has been installed by default on your system.

On top of this, you can still select what kind of kernel modules you want ot have installed (kABI, akmods and dkms).

The device files are created by the udev rules that call the nvidia-modprobe command, it contains a SUID binary that creates the device files and set the appropriate permissions. The same binary is called directly by Nvidia libraries when accessing a user space component that would require device files access:

$ for i in $(rpm -ql nvidia-driver-libs.x86_64 nvidia-driver-cuda-libs.x86_64 | grep \.so); do

This requires some testing and adjustments with specifics to your setup, but is definitely possible to use the integrated Intel card and or rely on a system without X installed to run the CUDA components.

CUDA

Packaging

  • Previously in the repository was included the GPU Deployment kit. This was constructed with NVML (NVIDIA Management Library) headers, docs and samples from a separate tarball. The separate tarball was using a different version number than the drivers and was packaged in the nvidia-driver-NVML and nvidia-driver-NVML-devel packages. Starting from CUDA version 8, the NVML header is provided by a CUDA subpackage (cuda-nvml-devel) and no longer provided as part of the GPU Deployment kit.
  • Included is also the Video Codec SDK (Decoder/Encoder) headers, docs and code samples. Again, this uses a different version than the drivers.
  • All the libraries are split into subpackages, much like in the original Nvidia CUDA repository. This allows you to install and build software relying on specific components without the need to install all the CUDA toolkit just to satisfy a library dependency. Also, for the same reason, static libraries have been included in each respective static subpackage.
  • In addition to the libraries bundled in the CUDA toolkit, also the cuDNN library for distributed neural networks is included in the repository. See the table below for details.

Distribution and CUDA version support

All the currently supported Red Hat Enterprise Linux versions (including rebuilds and similar forks – CentOS Stream, AlmaLinux, RockyLinux, EuroLinux, etc.) and Fedora versions are available.

In case of yet unsupported compilers in recent distributions, a compatibility cuda-gcc package is available that brings the distribution to a working level with nvcc.

By installing the cuda-gcc package, a variable is loaded automatically that adds the appropriate NVCC options to override the default system GCC when compiling:

$ cat /etc/profile.d/cuda-gcc.sh 
export NVCC_PREPEND_FLAGS='-ccbin /usr/bin/cuda'

CUDA installations

To install just a runtime CUDA support (required for running CUDA enabled programs), without DDX drivers:

yum -y install cuda nvidia-driver-cuda

To just install packages required for enabling CUDA development:

yum -y install cuda-devel

Or if you just want to enable everything:

dnf/yum -y install nvidia-driver nvidia-driver-cuda cuda-devel

A couple of examples. Just the basic tools:

This will avoid you pulling in all the libraries as before just because you need a single library. This is useful for example for programs that leverage just some part of the CUDA toolkit, like the Nvidia Performance Primitives for image and signal processing in FFmpeg, and similar things.

Just open an issue to the specific package on GitHub.

1,257 thoughts to “Nvidia driver, CUDA tools and libraries”

  1. Thanks for this awesome post. I followed it to install nvidia and nvidia-cuda drivers on a virtual machine running RHEL 8.6. Installation went well, but nvida-smi doesn’t work, I can’t start the driver. I am in over my head here, but it looks like I need to somehow sign the modules so they are able to run under secure boot. I can’t disable secure boot because this is an university computer. Any ideas?

  2. I need to support 1080 Titan Black cards but only see :510 drivers under any of the rhel x86_64 repos. Where is the :470 series?

  3. The CUDA libraries seem to be incomplete. You mention it is the “Complete packaged CUDA stack” but I had to install several additional libraries from the official repo. Some of these seem are “addons” (nvidia themselves used to keep some of these in separate “machine learning” repos) but others are fairly common.

    cuda-driver-devel-11-3 (or similar) – provides the stub library
    cuda-thrust-11-3 – provides a common C++ library for developing CUDA programs
    – also includes CUB, another great C++ library, which they put in with cuda-cudart(-devel) before 11.3 but you don’t have in your cuda-cudart(-devel)
    libnvinfer(-plugin)(-devel) – used for deep learning
    – ends up requiring NVIDIA’s official libcuddn and libcublas libraries, thus they are double-installed but luckily mostly in different location
    libcusparselt(-devel)
    libnvparsers(-devel) and libnvonnxparsers(-devel)

    I was able to install these side-by-side, but they end up in different location confusing things quite a bit. Additionally, the way the headers are placed in /usr/include/cuda doesn’t work for some standard tools/compilations since you cannot set the CUDA_PATH environmental variable and just be done with it. It is assumed that $CUDA_PATH/include will be the include directory, not $CUDA_PATH/include/cuda. And you can’t just change $CUDA_PATH since $CUDA_PATH/lib64 has to be something as well…

    1. Can you please open an issue at https://github.com/negativo17/cuda? It’s much easier to track.
      Stubs are not provided. If you have the libraries in separate packages and let depsolv do its thing you don’t need stub libraries as the packages get installed automatically.

      Looking into the other issues, sorry for the delay.

      1. Thrust and all the CUB & C++ headers are now part of cuda-devel. They were accidentally removed.
        I’m adding now the other libraries not provided in the runfile (libnvinfer, libcusparselt, libnvparsers) and the proper separate versioning of components introduced in 11.4.

  4. Hi, I’ve updated cuda to version 11.3 from your fedora33 repo: apparently thrust library is missing. I thought you moved it to a separate package as it is for other api libraries but I’m not able to find it. Can you please help me?
    Thank you
    (and by the way… thank you (a lot) for your work)

  5. Hi, it seems the thrust header library is not included in the Fedora33 11.3 (in 11.2 it was installed under /usr/include/cuda/thrust). I thought you might have moved it in a specific package as for the other libraries but a search by dnf did not reported any result for “thrust”. Actually some days ago there was a package cuda-thrust-11-3 listed under /repos/nvidia/fedora-33/x86_64 I tried to install it manually but it didn’t solve the problem. Now it’s not there anymore. Am I missing something? Maybe it is now in some other package?
    By the way… thank you for your work, a lot.

    1. Hello, it’s in cuda-devel:

      $ sudo dnf provides /usr/include/cuda/thrust

  6. Hi Slaneesh,

    Quick question: how is your versioning lifecycle works?
    for example when are you going to upgrade to latest 460 driver.

    Cheers,
    W

  7. I did:
    sudo dnf install nvidia-driver nvidia-settings nvidia-driver-libs.i686 dkms-nvidia nvidia-driver-cuda cuda-devel

    kernel-devel did not get installed as a dependency on my newly installed F33 Workstation. So I booted up into a fallback VGA driver (looked like 800×600).

    In order to get it to work I did the following:
    sudo dnf install kernel-devel
    sudo dkms install -m nvidia -v 455.28
    All the best,
    Dan

    1. dkms require kernel-devel-uname-r, which is provided by kernel-devel. Unless you’ve forced dependencies, you should have kernel-devel installed.

      1. I need the Linux 5.9 kernel to support my B550 Realtek 8125B 2.5G NIC. Nvidia drivers don’t support the Linux 5.9 kernel yet. Hopefully Nvidia will support the Linux 5.9 kernel by December.

  8. Just an FYI. Attempting to connect to the negativo17.org home page (at least from Ireland) results in a page not available/connection failed with my squid proxy. I can get to anything else but the home page isn’t working.

  9. Hi,
    I’m working on getting Steam to work on Fedora 32 with an NVidia discrete adapter doing the offload.
    I’m sure I’ll figure it all out eventually (combinations of VDPAU_DRIVER, and seven other environment variables, and maybe an xorg.conf.d/ file with a hidden Screen, not sure yet!).

    Since you package Steam, and you also (in a more Fedora-like way) package the nvidia driver, I think it might be a good idea to stop using the RPMFusion nvidia driver and start using yours.

    Do I need to set repo-priority or anything special to combine your repo with RPMFusion?

    1. Nvidia packages are just conflicting with the RPMFusion ones, while the multimedia repository is not compatible at all with RPMFusion.

  10. Hi, is kernel 5.8 already supported? i stuck at boot screen at ‘starting gnome display manager line’. Currently im using fedora 32 kernel 5.7.17 and its running fine. But i got stuck when im trying to boot using kernel

  11. First and foremost. Thanks for your repo. I’ve been using it for many years. Sometimes with kernel updates, I have to remove/install or dkms autoinstall. I just updated my Fedora to kernel 5.8 and I get that “include/generated/autoconf.h or include/config/auto.conf are missing”. Are you aware of any issues with the 5.8 kernel and Nvidia 450.66-1?

  12. Thanks for packaging all of the nvidia + cuda libs+tools!

    The latest version from the nvidia website is cuda-11, yet the repository you provide here is at cuda-10.2 – is there a timeline for when a update is being release for fedora 32 (if at all)?

    Much appreciated!

  14. Hi, I have installed the kernel 5.7.9-100.fc31.x86_64 and the negativo17 nvidia driver 450.57-1.fc31and the driver is broken. I have a laptos with dual card. Since fedora 28 I have been using negativo with not problems at all, but now for instance __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxgears does not run, and I get :

    X Error of failed request: BadValue (integer parameter out of range for operation)
    Major opcode of failed request: 151 (GLX)
    Minor opcode of failed request: 3 (X_GLXCreateContext)
    Value in failed request: 0x0
    Serial number of failed request: 25
    Current serial number in output stream: 26

    I do not know what it is the erro, when I boot with the kernel 5.6 happens the same. Any idea?

    thanks

  15. I installed updates this weekend, including the nvidia drivers -> 3.450, however compositing is broken now. I can disable it, but things are behaving well. (I am on Fedora 31 KDE spin)
    Is anyone aware of issues with this latest version?

  16. Thank you very much for providing nvidia drivers for fedora.

    Any idea on how to install ?

    1. Answering my own question about missing nvidia-kmod-common. At first I installed only the “fedora-multimedia” repo, but the “fedora-nvidia” should also be installed. Thanks negativo17, for providing these packages.

  17. Fresh installation of Fedora 32, installed drivers from nvidia-driver. After reboot I got 1024×768 resolution and no nvidia support. When I try to sudo modprobe nvidia, I get operation not permitted:

  18. Hi, thank you for your efforts to maintain those packages. Fedora already the xorg packages patched for use optimus technoloy with nvidia propietary driver. Could you have a xorg patched version on your el8 repository to use optmus in centos as well as we use on fedora?

    1. Hi, Nvidia drivers check for X.org server 1.20.7+ to enable the additional bits required for PRIME Display Offload Sink support and GPU screens. Not a big problem per se, as this requires just an updated X.org server. Unfortunately:

      • Due to the latest policy of not supporting all subpackages, the egl-wayland-devel packages are not available (try to download one here: https://koji.mbox.centos.org/koji/buildinfo?buildID=7013)
      • Rebuilding the CentOS/RHEL 8 egl-wayland package would be fine as well, but unfortunately this does not build anymore due to some compilation issues, as the dependent packages were originally at another version

      I would suggest on desktops to update to CentOS 8 Stream, in there you already have X.org server 1.20.8: http://mirror.centos.org/centos/8-stream/AppStream/x86_64/os/Packages/

      1 – Install this: http://mirror.centos.org/centos/8-stream/BaseOS/x86_64/os/Packages/centos-release-stream-8.3-3.2006.0.1.el8.x86_64.rpm
      2 – Update system & reboot

    1. After spending a day on the phone with GoDaddy, they informed me that they have an issue with the shared hosting and they can not update certificates on the various instances. According to them they had this issue on the past 3 weeks!

      Of course nobody bothered to tell me and now the certificate is expired and I have no way of fixing it. I will move everything to a separate hosting provider as soon as I can, starting from the repositories.

      Of course now it will be a dedicated box, so the cost will not be the same. Any donation is of course accepted.

  19. @SLAANESH

    Heads up!

    I am getting an expired certificate when using your repos and this website.

  20. Thank you for work with Nvidia and Fedora! Very much appreciated!

    Any idea when kernel 5.6.x support will be available? Fedora 31 moved from 5.5.x to 5.6.x and there no matching packages in the repo.

    Simultaneously Fedora 32 was released and I imagine it has the same issue??

    The newest packages in the repos are from April 9th, 2020.

    1. Hi, there is no binary kernel module being built for Fedora, that is only for kABI distributions like CentOS/RHEL. Either use akmod-nvidia or dkms-nvidia. Driver version 440.82 works fine with kernel 5.6.
      Just install the driver and you will be fine.

  21. Is /usr/lib64/nvidia/libOpenCL.so still a thing? I’m on Fedora 30, and am pretty sure it was here last June. Even “dnf provides” hasn’t a clue. Thanks!

    1. Can you check if you have both dkms and akmods installed? dkms is the one installing the kernel modules under weak-updates. If so, please remove dkms.

  22. Thanks for the great job.

  24. Anyone know if Ray Tracing is supported on Nvidia 20xx series? I can’t seem to get either Vulkan, RT, or both working. Not sure what’s going on.

    1. “Anyone know if Ray Tracing is supported on Nvidia 20xx series? I can’t seem to get either Vulkan, RT, or both working. Not sure what’s going on.”

      To update that. These drivers have Vulkan problems. Not Negativo’s fault, but Nvidia’s. I don’t recommend these drivers for Vulkan or Ray Tracing at this time.

  25. Never mind my last comment about how to fix it. Don’t know what happened there. For Fedora 31 there’s no 32bit before 440.xx. So kind of a bad situation until the problems are fixed.

  26. I’m getting the following dnf upgrade errors on my Fedora 31 installation. Looks like some conflicts with the rpmfusion packages.

    1. I ran into a similar problem as the 440.36 drivers were made available in RPMFusion.

      I fixed it by excluding all nvidia packages from RPMFusion non-free repository.

      This can be done by editing “/etc/yum.repos.d/rpmfusion-nonfree-updates.repo” and placing “exclude=nvidia” on a new-line within the “[rpmfusion-nonfree-updates]” of the file. Same can be done with “/etc/yum.repos.d/rpmfusion-nonfree.repo” and “[rpmfusion-nonfree]”.

    2. Late reply for you but might be helpful for someone else:

      Remove nvidia packages installed from rpmfusion.
      Add exclude option to rpmfusion-nonfree and rpmfusion-nonfree-updates repos config files in /etc/yum.repos.d:
      exclude=nvidia* akmod-nvidia xorg-x11-drv-nvidia*

      That option is per-repository and is a sanity saver when incompatible builds are available in multiple repos:

  27. Hi,

    sorry for asking here directly (I also asked on the Fedora forum but figured you might already know what might be the issue?)

    as recommended above (I too have a Thinkpad P51) but it didn’t help.

    Installed packages are

    nvidia-driver-cuda-435.21-2.fc31.x86_64
    dkms-nvidia-435.21-1.fc31.x86_64

    Many thanks for any help!!

  28. Hey, any chance for 32 bit libraries for Fedora 31 any time soon? I totally didn’t think that this might not be available when I updated today. Thanks for your work!

    1. They are now available. Had some personal issues to deal with (new kid and work!) and some hardware failures that took me much longer than planned to fix.

    1. I had the same problem too. Ended up installing F30 instead. I’d like to know what needs to be done to get 32-bit libraries installed. Steam won’t run without them.

  29. 435.21 seems to have broken fan control on secondary GPUs with no physical monitor attached. I was able to use the xorg.conf trick to make it think there was a screen attached previosuly, but this no longer works. I really hope this is a temporary regression, as we need the newer driver for DCC applications, but cannot use it without fan control for GPU rendering.

    Has anyone else come across this?

    1. I’ve done some research and it appears to be from the new Prime offloading business, which I do not need nor want. ugh.

    2. I got a response from NVidia, and it seems that the /etc/X11/xorg.conf.d/10-nvidia.conf enables prime offloading which causes issues with setup such as mine. It might be worth making a note that this is being done in case anyone else runs into the same issue.

  30. I’ve since added a bug report to the github repository: https://github.com/negativo17/nvidia-driver/issues/85

    On second thought, the issue might not even be related to those missing X.org commits. On the nvidia driver forum there is a thread about a similar issue: https://devtalk.nvidia.com/default/topic/1062922/linux/435-21-does-not-render-to-my-external-monitor/
    – it appears that the driver now defaults to render offload mode, but then it can’t use external monitors (at least on this laptop, where the HDMI output is connected to the dGPU only). I needed to put Option “PrimaryGPU” “yes” in the nvidia.conf config file in xorg.conf.d to switch it back to the old mode.

  31. It appears that the new 435.21 driver breaks hybrid graphics mode. I’m using a Thinkpad P50 with the laptop’s own display driven by the Intel chip and an external monitor connected to the HDMI output driven by the Nvidia GPU.
    Until yesterday with the previous (430.something) driver it worked nicely, today, however, the external display fails to wake up from power saving mode, and there are several other signs that the nvidia driver is somehow broken (xrandr doesn’t even report any monitors other than the laptop’s own, and nvidia-settings doesn’t start properly: when ran from the command line, it prints an error message about “ERROR: nvidia-settings could not find the registry key file.”.

    When I change the display setting in the BIOS to “discrete graphics”, which completely disables the Intel internal GPU, I’m able to use both displays, but then I don’t have graphics mode during the boot process, and in any case, I’m reluctant to switch to that mode, since there are several reports on the internet that doing so might brick the laptop.

    I’ll try downgrading the driver for now.

    1. Can you try to to comment the following line:

      # cat /usr/lib/modprobe.d/nvidia.conf | grep NV
      options nvidia NVreg_DynamicPowerManagement=0x02

      Then running depmod -a and rebooting? This makes sure the Nvidia card does not power off completely, it can just reach the lowest power state.

      Thanks.

  32. After the update to 435.17 driver and xorg 1.20.5-7.fc30@fedora-nvidia, as I understood, the prime offloading in xorg is enabled by default and system uses integrated intel gpu. But it looks like it never utilizes nvidia gpu.
    (@slaanesh, as an aside, why don’t you package nvidia-smi tool that comes with the nvidia installer?)

    Is it a misconfiguration/missing configuration, or do I need to provide extra config?

    Can you provide any pointers to resources where I can learn how this whole GPU system works? I am poking at things at random here and I don’t like that.

    Some basic info about system: https://gist.github.com/Xerkus/660574e28c7a9990318c5bf0dc79363b

      You have to start programs with the appropriate variables, for ex.:

      $ glxinfo | grep “OpenGL.*version string”
      OpenGL core profile version string: 4.5 (Core Profile) Mesa 19.1.5
      OpenGL core profile shading language version string: 4.50
      OpenGL version string: 3.0 Mesa 19.1.5
      OpenGL shading language version string: 1.30
      OpenGL ES profile version string: OpenGL ES 3.2 Mesa 19.1.5
      OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

      $ __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia glxinfo | grep “OpenGL.*version string”
      OpenGL core profile version string: 4.6.0 NVIDIA 435.17
      OpenGL core profile shading language version string: 4.60 NVIDIA
      OpenGL version string: 4.6.0 NVIDIA 435.17
      OpenGL shading language version string: 4.60 NVIDIA
      OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 435.17

      I will try to make a blog post, but I’m overwhelmed by work.

      (@slaanesh, as an aside, why don’t you package nvidia-smi tool that comes with the nvidia installer?)

      Just search for it, it’s packaged:

      sudo dnf provides \*bin/nvidia-smi

      1. I see. I had a wrong expectation of it working automagically. Kinda how it was for a while with the aim at the general user: just install nvidia driver packages and it is ready to go.
        Is it something that we can expect in the future when this new feature is mainlined?

        You have to start programs with the appropriate variables

        It is not too friendly for the users like my mom. She won’t know anything about gpu, much less any drivers or starting apps with different env variables.
        I found this tool https://github.com/wildtruc/nvidia-prime-select to select default active gpu. Would you consider it an appropriate solution? It seems to be using this exact new driver feature under the hood too, somehow.

        Just search for it, it’s packaged:
        sudo dnf provides *bin/nvidia-smi

        Oh, indeed. There was a bunch of cuda packages from rpmfusion and I didn’t notice one of them was actually from your repo. My bad.

        but I’m overwhelmed by work

        Thank you for finding time for this. You made my fedora experience amazing for years.

          It is ready to go. Add the drivers, and the discrete GPU is fine and powered off until you want to use it. That’s my definition of “just works”

          It is not too friendly for the users like my mom. She won’t know anything about gpu, much less any drivers or starting apps with different env variables.

          That’s exactly the point, why should she care about the GPU then?

          Anyway you can just add this to your Bash profile or the system wide profile:

          alias nvidia-run='__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia "$@"'

          Then you can just run, for example nvidia-run doom3bfg etc.

          Don’t use it, it generates a lot of X config that is actually not needed. If you have one of the old laptops where some output is connected to the Nvidia GPU, the GPU powers on accordingly, so also in this case there is nothing to do.

  33. When I update to 435.21 I lose audio device GM204 ( Audio from the gpu through HDMI ) and have to downgrade back to 430.40 Is there anything I can do to fix that?

    1. 430.40 is already in the repositories since the end of July. 435.21 soon, along with the patched X server for PRIME offload and updated X server.

  34. Thanks for your nvidia drivers. Have you ever considered providing the latest “nouveau” driver, the one supplied with the fedora 30 and 31 beta is still 1.0.15 (last 1.0.16)?

  35. After upgrading from 418.56 to 430.14 on Fedora 30, mpv and ffmpeg segfault, when trying to use CUDA for hardware acceleration. Both stack traces show the fault occurring in /lib64/libnvcuvid.so.1. It was working flawlessly with the older drivers.

  36. Is there a chance that we can have different versions of CUDA installed in parallel? It would be nice to be able to install them from the repos.

    1. Was planning to start using the modules in Fedora and RHEL 8, but had no time to work on it. For now, just use Nvidia provided packages which allow parallel installation.

  37. Unable to access repo on Fedora 27, Getting error:

    Failed to synchronize cache for repo ‘fedora-nvidia’, disabling.

    Any advice?
