[ale] X server dying

[Jim Philips]

More Ubuntu fun. I upgraded some packages for X and now the X server 
won't start at all. It seems to be dying with this message:

NVIDIA X Driver  1.0-8762  Mon May 15 13:09:21 PDT 2006
(II) NVIDIA Unified Driver for all Supported NVIDIA GPUs
(EE) No devices detected.

Fatal server error:
no screens found

What does this mean? Or how can I found out which update caused this? I 
am still fairly new to apt-get (and already hating it).
