are you using an nvidia card? If so, do you have nvidia-settings installed? If so, it's pretty easy, just run nvidia-settings as root, or via sudo (i.e. "sudo nvidia-settings") go the the "X Server Display Configuration" and change the resolution to how you'd like it. Once you're happy, click "Save to X-Configuration File" and you're done.
If you don't have nvidia settings, you have to do it the hard way (at least, that's the only way I know how), which is to edit your xorg.conf file. If this is the case:
sudo nano -w /etc/X11/xorg.conf
then look for a line that sayd "Modes ...."
on that line you will see your possible screen resolutions, the first one it sees is the one that is used, so add a new one at the beginning. Make sure to form it like the others, i.e. "1600x1200" - with quotes and no spaces. Leave spaces between entries, i.e. "1600x1200" "1024x768". Quit, save, & you're set.
When you're done, log out, then hit cntl-backspace (or just reboot) & you should be up with your new resolution. If it doesn't work, you'll get an error message, be dropped to an old-timey shell where you can edit out your last changes. in old-timey shell, the command "reboot" will restart your computer.
