Tumbleweed Backlight

Had some trouble getting xbacklight to work on openSUSE Tumbleweed, so I wrote this simple program that should work around it. Requires root, a workaround can be found at stackoverflow.

The values of the fname and max_fname variables might need to be changed to the correct path to your backlight brightness files.

Compilation:

g++ -std=c++11 -o twbl twbl.cpp

Usage (i3 config):

bindsym XF86MonBrightnessUp exec sudo /home/dzejrou/bin/twbl +100 # increase screen brightness
bindsym XF86MonBrightnessDown exec sudo /home/dzejrou/bin/twbl -100 # decrease screen brightness

TODO

• Create a Makefile
• Find a way to not need sudo
• (RFC) Maybe change granularity of increment/decrement (e.g. "./twbl +1" makes no difference at all, up until 1000)
