Linux hepl: changing screen resolution

[Kyteland]

I just got a Red Hat 7.something box at work and it must be set to 1600x1200@60Hz because it is driving me crazy. I looked in the /etc/X11/XF86config file and it has a huge listing of resolutions that are supported by the monitor including 1600x1200@85Hz. I know this is possible because the monitor is hooked up through a KVM to a Win2k box and I run that at 1600x1200@85Hz.

How do I go about switching screen resolutions without editing that file? The sysadmin would kill me if I started messing with things like that.

But seriously, is there any way to switch among the monitor settings listed in that file?

ctrl-del -/+ (on the number key pad)... I think.

That doesn't resize the desktop though, it just zooms. You will need to edit XF86Config[-4] to actually change the resolution.

if the mode line has more than one res, such as this:

Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"

then ctrl-alt -/+ will cycle through those modes

But like I said, it just changes the mode, not the desktop size. You will have to pan around your desktop with the mouse, which I would say is fairly useless.

Ok, thanks a lot. I'll back up my config file and try deleting all of the modes except for the one I want. Maybe I should try this on a box at home first before I screw up my computer at work...

Hm, maybe not.
