Computer is a Dell Dimension E521. The Dell monitor has a native resolution of 1440x900 at 60 Hz. However, the Knoppix 6.2 memory stick always boots to a destop with resolution 800x600. (That is the maximum listed in the resolution change tool.) I have tried various combinations of cheat codes "noddc". "screen=1440x900", and "vsync=60", but they make no difference.

Here is the "lspci -v" output. Any ideas?
