SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Instead of asking on forum i would like to ask directly developers, how to enable fully on SDDM AND KDE itself dedicated card. https://discuss.kde.org/t/how-to-make-nvidia-the-default-card-on-wayland/5233 *** STEPS TO REPRODUCE None, since theres no guide or none working. OBSERVED RESULT ubuntu tool to swap between driver versions fucks up as always, manually installed direct from nvidia site doesnt work, nvidia-smi dont see anything, or uselessly running xorg. without any other programs which should EXPECTED RESULT Run full power on dedicated card let it be used and use its computing power SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 23.04 (available in About System) KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.104.0 Qt Version: 5.15.8 ADDITIONAL INFORMATION ``` lsd@lsd-Crawler-E25:~$ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin" #KWIN_DRM_DEVICES="/dev/dri/card1:/dev/dri/card0" #GBM_BACKEND=nvidia-drm #[D__GLX_VENDOR_LIBRARY_NAME=nvidia #ENABLE_VKBASALT=1 #LIBVA_DRIVER_NAME=nvidial``` without hashes crashes all
Please do not set any environment variables like GBM_BACKEND, D__GLX_VENDOR_LIBRARY_NAME or LIBVA_DRIVER_NAME globally, they only cause problems. KWIN_DRM_DEVICES is all you need to do what you want, and has documentation here: https://invent.kde.org/plasma/kwin/-/wikis/Environment-Variables#kwin_drm_devices
doesnt work, propably nvidia drivers still are fucked even on latest highest number. hard hang after typing password. https://www.youtube.com/watch?v=veqdTlb5UYk lsd@lsd-Crawler-E25:~$ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin" #KWIN_DRM_DEVICES="/dev/dri/by-path/pci-0000\:01\:00.0-card:/dev/dri/by-path/pci-0000\:06\:00.0-card" In my case. https://mega.nz/file/m0ohGRiJ#0FbLgII9THQc70VIBy-pcVkNAkehoki_0BSW44qBSKQ
