[SOLVED] Nvidia + Wayland falls back to `llvmpipe` after recent `zypper dup`

[erfee]

Just wanted to share a solution to an issue I ran into after the latest zypper dup on Tumbleweed, in case anyone else hits the same problem.

My Setup:

• openSUSE Tumbleweed
• Nvidia GPU (Proprietary Driver)
• KDE Plasma with Wayland session

The Problem:

After a zypper dup today (2025-07-24) which updated the Nvidia driver to version 570.172.08, my Plasma Wayland session stopped using the Nvidia GPU for rendering.

The symptoms were:

• The desktop was running, but glxinfo showed software rendering:

  glxinfo | grep "OpenGL renderer"
  OpenGL renderer string: llvmpipe (LLVM 20.1.7, 256 bits)
  

• nvidia-smi showed that only Xorg.binwas using the GPU. No kwin_wayland or other plasma processes were listed.

• I noticed that the nvidia_drm module didn’t seem to be loaded. The directory /sys/module/nvidia_drm/ was missing.

The Fix:

After some digging, I found that a configuration file was changed during the update. A line that seems to enable the nvidia_drm module was removed.

1. The file in question is /usr/lib/modprobe.d/50-nvidia.conf.

2. After the update, this file was missing a specific install directive.

3. I re-added the following lines to the file (The comments were already in the old conf file together with the directive. So I put them together here ):

   # Use this default and let it win against
   # 'install nvidia-drm /usr/bin/true' rule in 60-nvidia-<flavor>.conf,
   # which comes with nvidia-open-driver-G06-signed-kmp-<flavor>, which avoids
   # this module being loaded without config and GSP firmware files. See also

   install nvidia-drm /sbin/modprobe --ignore-install nvidia-drm
   

After adding the install nvidia-drm ... line back and rebooting, the problem was completely solved. My Plasma Wayland session is back to using the Nvidia GPU for rendering, and glxinfo and nvidia-smi both show the correct processes.

I wanted to check the link to Bugzilla in the comment for more information, but it appears to be down for maintenance at the moment. I figured I’d post here in the meantime.

Hope this helps someone else out there
