I know the Computer --> Whatever --> Set Screen Resolution thing, but it doesn't list all the resolutions my screen can handle. Is there any way to set this higher than what is in the list?
PS: I did try google.
I believe it's configured in the xorg.conf or XFree86-4 files.
/etc/X11/xorg.conf
/etc/X11/xfree86.conf
It shoudl be one of those, or something like those, where you'll find a list of resolutions. Just edit that list, and restart X.
I think for XFree86 it's /etc/X11/XFree86Conf-4
If you're running on a nonstandard display, you might need a special modeline. For example, this is part of my xorg.conf:
Section "Monitor"
Identifier "Monitor0"
VendorName "hp pavilion"
ModelName "LCD Panel 1440x900"
HorizSync 30 - 64
VertRefresh 50 - 100
Modeline "1440x900" 97.54 1440 1472 1840 1872 900 919 927 946
Option "dpms"
