I have a Dell desktop with an NVidia GeForce4 Ti4200 graphics card driving a Dell Ultrasharp 19" LCD display (using the DVI connection). Knoppix 7-26 correctly identifies both; actually, the display is detected as "DEL3009", whatever that means.
However, I cannot get the 1280x1024 resolution (native to this display) to work--not even using xscreen=1280x1024. If I use the autodetected nv driver and xscreen=1280x1024, I get garbage on screen (diagonal bands that look like the desktop background); perhaps this is a modeline issue. If I use the fb1280x1024 driver, I get bumped out of X to the command line with an error message saying that no suitable mode for my display was found. Everything works just fine if I let Knoppix boot into 1024x768 mode, except that, of course, the picture is "soft", or fuzzy, because that is not the LCD's native resolution.
I have tried the SuSe 8.2 live eval CDROM, and verified that it does manage to get 1280x1024 working somehow. But I cannot say whether this is an NVidia problem or a Dell Ultrasharp problem---although I suspect the latter.
ANy ideas?
Thanks!
