After a new test...it seems to work "some time" with ubuntu 10.10 RC daily build from 06-Oct-2010 (64 bit) running from liveCD. In that case there is an other bug with extended desktop where panel refuse to "stay" on the laptop lcd (DP1) and is always on the external screen (VGA1)! Panels and Nautilus are displayed on VGA1 Applications such as Openoffice are displayed on DP1...
I am going to look for this bug in launchpad.... Cheers.
