Is there a command-line utility i can use to adjust the brightness or contrast of my X display?

You could take a look at xgamma, which you will have to run from a terminal or console:

man xgamma

xgamma can help slightly, but if your monitor is too bright or too dim you should be able to control it via the buttons on the front of the monitor or if it's a laptop there should be a function key that does it.

All my settings are maxed out for both MPlayer and monitor controls and video is playing too dark in MPlayer in Damn Small Linux 3.0.1.

did xgamma work for you guys? I had a similar problem a long time ago and this worked for me, I found no other solutions than replacing my monitor which I eventually did. Just put xgamma -gamma 1.0(1.0 is default change high for higher brightness obviously).

Bash command not found for xgamma. It is not installed on dsl. I wonder if it's even possible to get it installed on DSL. I'm having too many problems. I may try using DSL-n instead. I will keep trying many things and hopefully something will work.
