How do I fix corrupt video settings?
 

I am running Red Hat 9 and Windows XP on a Dell Inspiron 8600. Everything works fine, and like an idiot I went and screwed with it. I changed one of the video settings (I changed the video driver from the generic VESA that worked to nVidia GeForce FX, which is what's in the laptop). It said to logout for the settings to take effect, and as soon as I did, the screen went all garbled. I can't see what's going on, so I can't get in there and change it back... can I reset this from the console or something?

is there an option at the login screen to start in something similar to 'safe mode'? does xwindows load automatically?

I can get at a command prompt pretty easily, when red hat is loading it does the filesystem check because I keep shutting it down improperly. So yeah, I can get at a command line, but no graphical safe mode that I know of.

Don't keep doing that or you may have worse problems soon.

If you are using the grub menu, highligt the linux entry.
Type: e
Highlight the line with kernel information and type: e
Go to the end of that line and space over once, then type: init 1 and press enter
Now type: b to boot up in level one ( init 1 ) . That should get you to a command line and logged in as root user.

Type: redhat-config-display for older Redhat versions.
For newer versions like FC3, use the command: system-config-display .

That should give you an opportunity to select the proper monitor and video card settings.

When you are done, you can use the command: init 5 to get into the normal gui mode.
