It is possible reproduce on 10.04 (lucid)
With supported nvidia driver 256.52 it works fine.
With PPA buntu-x-swat/x-updates driver 270.29-0ubuntu1~lucid~xup2 it fails.
It looks like problem on nvidia drivers, but I am not able to find any similar bug report on http://www.nvnews.net/vbulletin/forumdisplay.php?f=14

Note that the problem is rather serious on Ubuntu 11.04, as it is not possible to use older drivers as a workaround. The new Natty xorg-packages use ABI 10.0, which is only supported by the nVidia drivers >= 270.41.06.

Option "ProbeAllGpus" "true" can be used as workaround. Tested.
