I tweaked my Linux box too much!

    I know you know the old saying, "If it's not broke don't fix it." I
was trying to "tweak"
my X Window System display by running XF86Setup utility. I had had a
nice display setup already but I thought if I tinkered with it some more
I could get pictures to be little sharper than they were in netscape. (
I have a 4 MB AGP Diamond Stealth Card ) After I changed some settings I
saved them and exited the program. When I rebooted the system, it went
through the standard boot-up routine except when it got to xdm my screen
went blank and everything locked up. I figured that if I new how to
disable xdm, I could boot up to just the Linux command line and run
XF86Setup again, but I do not know what config file to edit in order to
disable xdm.
