Xmonad.Util.Brightness missing AMD support.

Question

Xmonad.Util.Brightness missing AMD support.

qcc-na opened this issue 5 years ago · comments

The documentation on hackage assumes the presence of an intel backlight.
http://hackage.haskell.org/package/xmonad-extras-0.15.1/docs/XMonad-Util-Brightness.html

Requirements
    This module assumes that the following files exists:

        /sys/class/backlight/intel_backlight/max_brightness
        /sys/class/backlight/intel_backlight/brightness

I'm on a thinkpad(A485) with an AMD gpu and would greatly appreciate amd support and in fact would be willing take this effort on myself.

I'm not sure where the amdgpu_bl0 comes from or if it would even be consistent across amd gpus.

$ ls /sys/class/backlight/
amdgpu_bl0

What do ya say?

@qcc-na Sounds good to me. Can you create an working PR for this ? We can take it from there.

I moved past this issue by having acpid run a script when I hit the brightness button.

I haven't made any progress on a pr. You can close if you want.

@qcc-na I'm closing the issue now. Free feel to re-open it if you plan to implement this in future. Thanks!
