I have been trying to get the screen to X window to fit with my screen, but have not had any luck when using Fedora 6. I works fine with RHEL 4 but after installation of F6 I haven't been able to get the screen to match up. I have played around some with the H-sync and V-sync but have not been able to find one where I can see the tray at the bottom. This is a 1680x1050 resolution screen, but the best I can get is 1440x900 which still has the problem with the vertical being too large.

I also have been having trouble with the mouse disappearing when I try different resolutions.

    Try adding -  "1680x1050" - to Modes   -----gary

I've tried that and it doesn't help. I've also noticed that whenever I logout and then log back in I lose my mouse. I mean it is still there, I can mouse over stuff and see a response, but I can't see the pointer.

I would start my debugging by looking closely through the Xorg
log file (/var/log/Xorg.0.log).

It should somewhere in there report what modes it thinks are
supported by your monitor, along with lots of other good info
including values you might need to craft a custom Modeline.
