At lxqt-config-globalkeyshortcuts to adjust brightness by default assigned
It don’t work. Although lxqt-config-brightness works fine from QTerminal.
I change lxqt-config-brightness to xbacklight (inc/dec). And keys begin work.
The problem seems to be solved, but I’m just wondering why lxqt-config-globalkeyshortcuts don’t bind keys to lxqt-config-brightness and sucsessfully bind to xbacklight?
