A sort of esoteric question:

Long story short, I bought a new 21inch monitor which didn't entirely work. Whlie using it, I changed to a extremely high resolution, not knowing it was about to fail on me. Now, a new monitor is on the way but I'm forced to use a 19inch monitor in the interim, and I turned it on to discover that it won't display as far as my graphical login and I can't log in to change the settings in X.

Using RedHat 9.1, is there any way to change my resolution without logging in, or a way to stop the machine from going to a graphical login?

(or maybe something else I've overlooked?)

Any help's great.

Sorry. To clarify: it's out of scan range, I mean.

Boot into console mode and edit your XFree86 config file to change the scan range.

I'm sorry to ask, but... how do I do that, really?

I've checked google but I can't seem to find anything. Is it one of the GRUB commands?

When the Grub menu boots up press 'e' to edit then add a 3 to the end of the first boot line to stop it booting into graphical mode, then boot.

Edit the settings in XF86Config for your monitor using vi or whatever program

it should be in /etc/X11 directory

From the command line, try either xf86config or XFree86Setup.
