@gonzo_s: wow. Thanks for the kind words.
I am currently using 256.35 from the ppa:ubuntu-x-swat/x-updates
I followed the instructions here: http://www.webupd8.org/2010/03/how-t...mment-41037671
to get the plymouth splash looking better.
Web page scrolling actually improved going from the 173 driver from the ubuntu repo to nouveau.
with 180 and 185, there was a tremendous delay when logging a user out before I would get back to the GDM login screen, and sometimes it would pop up saying that ubuntu is running in low grapics mode.
Is there a way to improve the speed switching users?
