Gonzalo San Gil, PhD. on 11 Jul 16" 80 down vote favorite 43 To work around bug #1005495 (changing LCD brightness via hotkeys impossible), I'd like to have one command line query for increasing and one for reducing the brightness of my LCD. I could then map a hotkey to each one of this queries. The problem is: I don't know how to increase and reduce the LCD brightness on the command line. Do you?"
