I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I have the same problem on my laptop fujitsu siemens V6515, ubuntu 9.04 ; nVidia Corporation GeForce 9200M G .
Driver 195.36.15 Thu Mar 11 22:01:49 PST 2010.

The screen resolution (800x1280) looks much better when windows-xp runs on the same machine.
Ubuntu says it use the same resolution - but its a lie...
