Frank, Thanks for the hint. I found the corresponding info and hand edited a new xorg.conf file. I still get an "Out of Range" error for 16-bit color at 1920x1200. The highest resolution I can get is 1440x900, and even that overscans the available screen. Is there something else I'm missing? --Doc Savage Fairview Heights, IL
