Bug ID: 449106
Summary: Discrete graphics card not detected on Pop OS 21.10.
Product: plasmashell
Version: 5.23.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: yuri6...@yuristudio.net
CC: plasma-b...@kde.org
Target Milestone: 1.0
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
***
I've recently switched to KDE 5.22.5 which is available through normal Pop OS
packages. I did that switch to avoid the repetitive crashes with GNOME/VLC and
recover the good old global menu I'm missing from Unity 7 era.
STEPS TO REPRODUCE
1. Right click app in start menu.
2. Go to "Properties" then "Application" then open advanced settings.
3. Enjoy the GPU section missing.
OBSERVED RESULT
The GPU section is missing.
EXPECTED RESULT
The GPU section should appear.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Pop!_OS 21.10
(available in About System)
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
My hardware is a dual GPU system Intel UHD + NVIDIA RTX 3060. This is a laptop.
The GPU works properly in hybrid mode as modifying apps in "Application" menu
by adding the "env __NV_PRIME_RENDER_OFFLOAD=1
__GLX_VENDOR_LIBRARY_NAME=nvidia" prefix does indeed launch apps on the RTX
3060 (verified through nvidia-smi). Using these env vars in terminal also works
as expected. CUDA apps also works. This is only a plasma issue where plasma is
unable to detect that the system is configured as switchable hybrid graphics.
The driver in use is NVIDIA proprietary with NVIDIA prime. Driver version is
470.86.
