I think this bug is also biting me.

I installed the final 11.04 on my Thinkpad 410s ( Arrandale / Intel(R) Core(TM) i5 M 520 w/UMA graphics ), and my external monitors both at home and in the office worked just fine as extended desktops. Since I bought it, this has been the first Ubuntu laptop I've had that I could just plug the external monitor in, and it just *worked*.

I updated the system the following Monday after the final release, and my external monitor support broke. I get a visible top panel on my external monitor, and a blank desktop. If I drag a window from my builtin LCD to the external monitor, it's not visible. I tried fooling around with the Monitors settings application to no avail ( and sometimes Compiz crashes ).

I tried backing down the xserver-xorg-video-intel package from 2:2.14.0-4ubuntu7.1 to 2:2.14.0-4ubuntu7,
and it made no difference.

When I backed down from Unity 3.8.12-0ubuntu1 to 3.8.10-0ubuntu2, my external monitor started working again.

Please let me know if there's any additional information I can provide.
