Yes. I had to do it just this morning, in fact.
First, at the command line, as root, do
cp ./xorg.conf xorg.conf.safe
--so that you'll have a backup of the file in case you really mess it up by accident.
Still as root, run vim or another command-line editor and edit /etc/X11/xorg.conf so that the section called
"Display" for the color depth currently in use on your machine has a line that says "Virtual 800 600" if that's
the resolution you want; "Virtual 1024 768" if that's your desired setting, etc. In other words, horizontal

to read the resolution you want. It will only pick up on the one that matches your color depth.
I hope you know how to use a command-line editor. If not, do "man vim" and pick out the essentials. It's
really easy to do the BASIC things with vim (or vi, if that's the version you have, but you probably have vim).
Or do a search here, or elsewhere, for a vim tutorial or tips. There are threads here where the essentials
were spelled out for users in a jam like yours, so searching for keyword "vim" ought to turn up how to do
what you need to do, if you're unfamiliar with vim.
After you've made the change to the resolution settings, log out and log in again as normal user, start up X, and you ought to
