Back into my K/Ubuntu installation without re-installing. That was a time
saver! I used the recovery console to go through each xserver-xorg package.
One was missing (xserver-xorg-nv) and after I used apt-get to install it and
re-booted it worked fine.

I am not sure why it could not mount the file system as it is working, too.
Strange things have been happening. Let's hope the trend does not continue.

The first alpha of Lucid comes out on Thursday, if you have a spare
partition or want to run it in a VM. It seems that we need more testers from
alpha to final to silence the critics that came out of the woodwork against
Karmic.
