Knowledge Base

Years ago I found a small program on the Internet that makes it easier to adjust screen brightness within X11. You can of course use xrandr, but this makes it easier when you're not thinking that deeply.

It isn't sufficient for adjusting gamma. I need to adjust gamma for playing games like Portal that are just too dark.

xgamma -gamma 1.5

Maybe I should add it as a slider, but I haven't bothered to do that yet.
