After upgrading from Debian Lenny to Debian Squeeze and opening XFCE, i find that the colors appear "washed out" or "too light." On top of that, the screen resolution defaults to 1440x900 which is inappropriately big for the monitor i'm using. I suspect this has something to do with xorg & hal misidentifying my hardware. I can fix the resolution with xrandr but how do i fix the color?

Running on various server class video cards including ATI ES1000 through a Black Box KVM over Cat5 system. I suspect the KVM system is what's confusing xorg and hal.

This question came from our site for system and network administrators.

The display's gamma settings need to be calibrated for better display. A tool like GAMMApage can help tune the colors of the display. GAMMApage in particular, then applies an xgamma command to your X startup scripts to have those settings applied at every login.
