GNOME: Setting screen resolution?

[Joe]

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.

[iago]

/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"
