Can't install NVIDIA drivers in Fedora 40

adityasz · April 26, 2024, 3:23pm

After upgrading to Fedora 40, dkms.service didn’t start and nvidia-smi didn’t work:

NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I install NVIDIA driver (for my Ampere card) and CUDA from the CUDA repos, and this method always worked in Fedora 38 and 39.

RPM Fusion contains incorrect instructions as usual, which lead to stupid errors:

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages)

I tried several reinstalls, with and without the nvidia-drm.modeset=1 parameter. sudo dkms autoinstall resulted in compiler errors, probably because of GCC 14 (Fedora 39 had GCC 13). How can I get a pre-built GCC 13 binary on Fedora 40?

Added f40 and removed f38, f39

So I got the driver installed using the runfile (not recommended, but it always works).

Can’t get CUDA to install from the runfile though.

Edit: pass --override to the CUDA runfile (to prevent gcc 14 related errors) and don’t install the driver that it contains (so install the driver from the other runfile separately).

My GPU is stuck at 80 W though even after starting nvidia-powerd.service (dissipated up to 140 W earlier).

GPU also doesn’t go into d3cold now.

You may want to try uBlue images, which are based on Fedora 40 and include the Nvidia driver.

I got it to compile with GCC 14. The errors are pretty straightforward to fix (only 4 lines need to be changed in source). Now the GPU goes into d3cold and enabling nvidia-powerd.service sets power cap to 140 W as well.

Edit: just change lines 112, 113, 115, 116 in /usr/src/nvidia-550.54.15/nvidia-drm/nvidia-drm-gem.c to

#if defined(NV_DRM_GEM_OBJECT_VMAP_HAS_MAP_ARG)
    .vmap    = (int (*)(struct drm_gem_object *, struct iosys_map *)) nv_drm_gem_vmap,
    .vunmap  = (void (*)(struct drm_gem_object *, struct iosys_map *)) nv_drm_gem_vunmap,
#else
    .vmap    = (int (*)(struct drm_gem_object *, struct iosys_map *)) nv_drm_gem_prime_vmap,
    .vunmap  = (void (*)(struct drm_gem_object *, struct iosys_map *)) nv_drm_gem_prime_vunmap,
