Hi, I recently installed manjaro with awesome wm, and it has worked great, apart from the brightness and volume keys. I did a lazy fix for the volume keys by adding a custom key shortcut to my rc.lua:
awful.key({ modkey }, "=" function ()
awful.util.spawn("amixer -q sset Master 5%+") end,
{description = "volume up (%5)", group = "volume"}
This works for volume, but i wanted to do the same for Brghtness, i found that i can adjust brightness with xrandr --brightness so i can adjust via the terminal with xrandr --output eDP1 --brightness #brightness 0.1-1 and change brightness, i want to do this in a increase of 10% and not to a fixed value so +10% or -10%, how can i do this?
–brightness brightness
Multiply the gamma values on the crtc currently attached to the output to specified floating value. Useful for
overly bright or overly dim outputs. However, this is a software only modification, if your hardware has support
to actually change the brightness, you will probably prefer to use xbacklight.
