If it's anything like my server updates this morning, my nvidia drivers for
my XFX were wiped.
I can't start x either, due to 'low graphics mode' and the most god-awful
mess on the screen (its unusable), so I'm relegated to terminal mode only at
the moment.
What is the graphics card you've got...
Check dmesg (there's probably a seg fault there related to X server).
I'm a bit puzzled as to how to fix mine as well, but I'm working on it (I
also have sent a message to the group this morning on these woes).
Even if I reboot into the last kernel I still have to manually tweak the
graphics settings to get a really low-res desktop, but my primary display
(Dell 1503FP digital) doesn't work at all.
Luckily my 42" plasma tv is plugged into the secondary dvi port and that's
what comes up... it's a challenge.

Jack
