XFCE openRC brightness setting, suddenly not giving effect
The brightness setting, on XFCE openRC, suddenly not giving effect at all, only responded GUI mouse click,
what package is brightness setting is in so it'll be updated ?
This likely due to the /root directory accidentally got deleted as happened next to then
Any correct idea to solve in shortest & simplest time & way? thanks before
