Probably, assuming you want to reduce the brightness. A desktop environment might provide something (my laptop now runs xfce, one of the panel plugins provides that), but in the past I've used xrandr. xrandr --output <name> --brightness <value> You'll need to discover the output names on your own machine xrandr --verbose | less and look for the 'connected' item (usually a variant of DP, HDMI or VGA). A value of 1.0 is full brightness, which is what you currently have. Try different settings (maybe start at 0.75) and see if you can find a value which suits. ĸen -- Vetinari smiled.
