Try this: Reboot. When you get the black screen, hit CTL-ALT-BKSPC
simultaneously. This should shutdown the X-Server and drop you to
a terminal. If it doesn't, post back here with the details. This
should be a root terminal. Read the output on the screen as to what
went wrong.
Note that X now by default disables control-alt-backspace now. This
is an Ubuntu page but it documents it.

Meanwhile it can be enabled again. I always enable it. Along with
setting a Compose key. I will throw that in here as a freebie.
setxkbmap -model pc104 -layout us -option compose:menu -option terminate:ctrl_alt_bksp
Ah! The classic Can't-leave-it-alone-until-I-fix-it masochist. They
have a support group for that. We meet every Tuesday at 7. Use my
name to get the fresh donuts. ;-)
Love it! :-)
