You can resetup the xorg.conf file by running:

sudo dpkg-reconfigure xserver-xorg

Also sometimes a line in the xorg.conf file "Virtual 1024x768" or 
similar causes some screens to 'scroll' or not look proper, usually with 
the logon or kdm screens...  Usually removing this line from the conf 
file fixes this.  It seems that hardy really removes alot of sections 
from the conf file (uses defaults) so there's no template to go by...  
You can look though mine if it helps. Don't copy it as the bus id of the 
card and many other things are not right, but it gives a good template 
to go by.  BTW i'm using a later Nvidia card and compiz-fusion.
