When I first began to use manjaro, everything was good. Then I wanted to use electron apps with hardware acceleration enabled in the settings of those apps.
When I disable hardware acceleration, these apps perform well, so thats what I did for most of the apps which provide such setting.
Recently, I tried stable-diffusion locally and their support guy told me that my system thinks it has a GPU, which would be the reason for the stable-diffusion not working (in the end he made stable-diffusion switch to a mode where the GPU driver didn’t interfere and that worked). He found that out when he told me to use the following command:
grep amd /proc/bus/pci/devices
My output of said command:
0800 10021636 45 c6000000c 0 c7000000c 0 1001 fd300000 0 10000000 0 200000 0 100 80000 0 amdgpu
Now I am suspecting that the slow apps when turned hardware acceleration on might somehow be linked to manjaro thinking it has a GPU inside and I would like to ensure that there is the right driver installed.
So far I:
- am unsure if I could just remove the amdgpu
- am unsure if that same amdgpu is behind “video-linux”
- read about amdgpu that the driver seems to be for graphic cards (which I don’t have in this laptop)
Some more information I while I searched for similar cases and used their same commands to compare my system to their case:
