F43 KDE Running Plasma using Nvidia GPU instead of AMD iGPU by default after upgrade

Ask Fedora
, ,
1

I have dualGPU Legion laptop with RTX 4060 and AMD iGPU.

Before things broke for me

  • Had everything working for more than 6 months.
  • Got an update pop up on Discover Software center.
  • Upgraded. Broke my Application Launcher on KDE.
  • Ran dnf upgrade and noticed gstreamer conflicting with qt dependency.
  • dnf remove gstreamer1-plugins-good-qt6 and did dnf update
  • It updated lots of other packages.
  • Rebooted. Plasma suddenly feels laggy, Laptop fans spins up.
  • nvidia-smi and noticed that Plasma session for some reason is using Nvidia GPU as primary.

Debugging

  • Uninstalled nvidia driver following RPMFusion guide.
  • Rebooting fixed issue but no nvidia drivers means no gaming.
  • Installed nvidia drivers again ( akmod and dracut finished ) and reboot.
  • Back to everything running on Nvidia GPU.

Please guide me. coz it’s unusable for daily needs if everything runs on bottomless power hungry Nvidia GPU

Edit: There’s no additional nvidia generated configs or anything. It’s all default.

More context if it helps

There is an update that may fix the issue.
You might be able to reinstall the gstreamer1 package with
sudo dnf --refresh --enablerepo updates-archive install gstreamer1-plugins-good-qt6

There was (today) an update that provided the newer package to resolve that conflict, but as I just found out it has not yet propagated to all the mirrors, so you may need to use the updates-archive repo which gets it at the same time as the updates repo. Packages in the updates repo are propagated to the mirrors, but the archive repo is not.

Nope.

➜  ~ sudo dnf --refresh --enablerepo updates-archive install gstreamer1-plugins-good-qt6
No matching repositories for updates-archive. Add "--help" for more information about the arguments.

I’m fine without gstreamer but why is KDE Plasma picking up Nvidia GPU as default now when it should be running on low powered amd-igpu instead? That’s the main issue I have.

Nothing has been altered in rpmfusion nvidia packaging, if plasma is defaulting to nvidia it might be something they changed.

Or maybe a kernel issue or something is delaying amdgpu driver from starting first.

7

The gstreamer1-plugins-good-qt6 version 1.26.7-4 is now in the fedora repos so the command sudo dnf upgrade --refresh should pull in that package.

Got new updates so I updated. Rebooted. Everything back to normal. Plasma now runs on amdgpu.
