Xorg with Nixos on an M1 macbook air seems to be very sluggish. #83

Closed x0ba closed 11 months ago

x0ba commented 1 year ago

I wrote up a basic home-manager + nix flake config for my m1 mac, and i'm using the same awesomewm config as what i used on regular asahi alarm. however, awesome on Nixos is noticeably slower, with workspace switching taking upwards of 1 second and the CPU usage of X spiking up to 50% every time a window is opened. Programs that used to work perfectly in asahi alarm, such as alacritty, now cant seem to use the graphics driver as they run very slowly. I have opengl and the edge kernel enabled, the relevant part of the config here

I would really appreciate if someone could tell me exactly what I'm doing wrong,

I don't see hardware.asahi.useExperimentalGPUDriver = true; set in your config.

If you run glxinfo you can see the current driver being used. llvmpipe is the cpu renderer. Apple ... will be the gpu:

# cpu renderer
$ glxinfo  | grep 'OpenGL renderer string'
OpenGL renderer string: llvmpipe (LLVM 15.0.6, 128 bits)

# gpu renderer
$ glxinfo  | grep 'OpenGL renderer string'
OpenGL renderer string: Apple M2 (G14G B0)

I use none+i3 and have a pretty sluggish experience. However, Firefox has proper GL acceleration (tested via WebGL). I reconfigured things to use a proper DE, which was smooth. I haven't spent the time to figure out what's going on with i3.
