What GPU driver(s) are you using for graphics on your computer?

foldfree commented 3 weeks ago

I am using asahi, the linux for apple silicon. It has an opengl and vulkan driver. https://gitlab.freedesktop.org/asahi/mesa

i rolled back to the previous build from the day before and things works. So something must have happened between the 2 days?

lilyinstarlight commented 3 weeks ago

I mean it's entirely possible something changed in nixpkgs (such as mesa/libdrm) and/or your kernel rather than anything cosmic is doing. Would you be willing to share drm debug log? (e.g. you can enable debug logs via something like boot.kernelParams = [ "drm.debug=0x1ff" ]; (I'm not 100% sure though and am on mobile or I'd double check))

Thank you, you were right. I downgraded the kernel and it worked!
