I’m on Bazzite using GNOME on a Frameworks laptop. When I scroll up and down, move to the apps bar, or sometimes just randomly, the screen will often glitch and show green/purple static in horizontal bars across the screen. I’ve got Bazzite and Windows dual booted, and when I use Windows I’ve never had this problem. Help please?
Hey,
try running:
sudo rpm-ostree kargs --append=amdgpu.dcdebugmask=0x10
then reboot and check to see if it’s resolved.
Tried it and it didn’t seem to change anything.
A friend said it’s a display driver issue with the kernel. I don’t know what that means or how to fix it but we can’t find what the package manager is for bazzite (i’m new to linux).
0x10 mask didn’t work for we either, but 0x410 works just fine. Unfortunately I am not so sure what is the difference here as I couldn’t find any documentation with exact mask values but hey, you can always roll it back!
sudo rpm-ostree kargs --append=amdgpu.dcdebugmask=0x410
and to remove (if you had) previous mask run
sudo rpm-ostree kargs --delete=amdgpu.dcdebugmask=0x10
Also please make sure you have AMD GPU for it to work. If you have Intel iGPU with this issue please try: (although I am not sure if that would even work)
sudo rpm-ostree kargs --append=i915.enable_psr=0
