[NTLUG:Discuss] I screwed up

[Preston]

You might try while it is loading, or even after it has booted to the Xwindows 
system to hit CTRL+ALT+F2, that should switch you to a command line login 
prompt.  (typically somewhere between F4-F7 is the Xwindows screen).  Login 
as root.  Find your XF86Config (using locate or find, mine is in /etc/X11 
which is where I would expect it to be, but sometimes RH puts stuff in weird 
places.  Open the XF86Config file with jed, emacs, vi or some text editor.  
Scroll down through the file and look for a section called "Screen" Under 
screen you will see a default depth, subsections with names, depths and modes 
somewhat like this:

Section "Screen"
  DefaultDepth 16
  SubSection "Display"
    Depth      15
    Modes      "1024x768" "800x600" "640x480"
  EndSubSection
  SubSection "Display"
    Depth      16
    Modes      "1024x768" "800x600" "640x480"
  EndSubSection

Look at all subsections and remove sections with depths your monitor cannot 
display and modes (resolutions) within subsections that your monitor cannot 
display.  Restart x, or just restart your computer.  Hope this helps.
