Changing screen resolution

By barry ·
I installed CentOS 4.1 with Graphical Interface On - starting up using Gnome. I modified the screen resolution to 1280 x 1024. All worked well.

I just moved my server to a new location which has a standard 15' VDU (which doesn't accept 1280 x 1024 reolution). When I boot up, the screen goes blank. I had to change the runlevel back to 3 to get the system to boot in text mode.

Can anyone please tell me how I can get into the system (short of carrying in my 21' VDU) to run X-configuration in 800 x 600?

You insight and direction would be greatly appreciated. Thank you.

The config for your X server will be in a file named /etc/X11/XF86Config

or something along these lines

there is a section: named "screen"
or something alike

With Display subsections.

From these remove the 1280x1024 option and higher, and be sure you leave the 800x600 there.

Now the X server is forced to start in 800x600

And after the changes you can toggle through your remaining choices in the config file with "Ctrl,Alt + and -" while in the GUI. Just in case something would look better at 640 X 480 and then jump back to your default setting. Good luck.
