That gives me the name of the display I need to specify in the -output portion of the xrandr command I want to use to adjust the screen brightness.įor me, 50% is just about right on this particular screen, so I tested the command in the terminal with this syntax to set the brightness at half its normal value: VGA-1 disconnected (normal left inverted right x axis y axis) LVDS-1 connected 1600x900+0+0 (normal left inverted right x axis y axis) 345mm x 194mmĭP-1 disconnected (normal left inverted right x axis y axis)ĭP-2 disconnected (normal left inverted right x axis y axis)ĮDP-1 disconnected (normal left inverted right x axis y axis)ĭP-3 disconnected (normal left inverted right x axis y axis) ![]() The xrandr command was already available, so the first thing I did was run the following in a terminal to see what the display name was on this laptop:įor me, on this particular laptop, it resulted in this (and I bolded the part that I was specifically looking for): However, the keybindings don’t work for adjusting the screen brightness, and I had to struggle for a bit to figure out how to get them properly mapped to this functionality.
