X failure after upgrade to Meerkat (Ubuntu 10.10)

[Bruce Labitt]

  Anyone know where the X stuff is hidden (umm, normally 
stored) in Ubuntu so I can get X to work again?

Context: 10.04 machine, freshly updated, then took the bait 
of going to 10.10 last night.  (An auxilliary machine, 
nothing important on it yet.  Trying to get koha running on 
it.)  During the upgrade, there was a failure in downloading 
a chinese ttf font.  System claimed to recover by running 
dpkg --config -a and said all was ok. When it started for 
the first time I got the Ubuntu 10.10 splash - then much 
churning, and finally dumping to console.  The error that 
seemed to pop up was it could not find the nvidia driver.  
Despite the obvious reasons why nvidia s*cks, why would 
10.10 decide to dump nvidia support?  The video card in 
question is OLD, but it is good enough.

So how does one start the X configuration again?  IIRC, 
there used to be routines like xf86config, etc that could be 
used to reconfig X.  All I need to is to get the screen 
going again at some half decent resolution.  Eventually, it 
would be nice to have something like 1600x1080 or so.

Or, since the driver seems to be missing, where to get it?  
IIRC since it was proprietary it needed to be downloaded 
differently, or from a different place.
