Comment 8 for bug 462168

OK, managed to get it working with lucid. Needed information from this thread: http://70.87.46.147/vbulletin/showthread.php?p=2252094

The important bit was using 'connectedmonitors' only once.

My xorg.conf now looks like:

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildmeister@builder58) Thu Apr 22 20:36:15 PDT 2010

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder58) Thu Apr 22 20:35:23 PDT 2010
