I have a Hanns-G 19 inch widescreen lcd. I’ve configured the X server using SaX2 and it works properly at the maximum resolution of the monitor (1440x900), but for lower resolutions it’s all messed up. KDE Display control panel doesn’t list some of the widescreen resolutions (1280x800), and 640x480 and 800x600 display parts of the desktop offscreen. In addition, there are lots of gibberish resolutions as well (576x432, etc.)
Here is my xorg.conf

I am guessing I have to provide modelines for the other resolutions as well?
