Brightness controls not working on Gigabyte display
We wrote some crummy code that adjusts it with xrandr – depending on whether the file is named brighter or darker – and then I bound it to some soft keys. The xrandr setting does not survive suspend though.
#! /usr/bin/python
import os,sys,time
delta=0.0
if sys.argv[0].find('brighter')>0:
delta=0.05
elif sys.argv[0].find('darker')>0:
delta=-0.05
default=0.4
minimum=0.05
maximum=1.5
brightfile=os.environ['HOME']+'/.bright'
try:
brightness=float(open(brightfile,'r').read().strip())
except:
brightness=0.4
brightness=max(min(brightness+delta,maximum),minimum)
cmd='xrandr --output eDP-1 --rate 60 --mode 1920x1080 --brightness %0.2f' % brightness
os.system(cmd)
if time.time()-os.stat(brightfile).st_mtime > 1.2:
notify='''notify-send -u low -a xrandr --icon=video-display 'OLED brightness' '%s' ''' % cmd
os.system(notify)
open(brightfile,'w').write('%0.2f\n' % brightness)
