I am using Ubuntu 11.04 Natty on Lenove Thinkpad T400. The video chip is Intel GM45. I have the same problem when connect to external monitor. And since I need to move between workplace and meeting rooms frequently, it becomes even bad for me.

You can see that when I connect the cable to a external monitor, then start Monitor Preference, the 'Laptop' lable is already displayed somewhere below the top-left corner.

When I enabled the external display which is a Lenevo Group Limited 20", then the screen on the external monitor will display in black with only a top panel.

Now the only way to have them work is to choose 'Same image in all monitors' .

But anyway, the external monitors as well as barcos in our meeting rooms worked fine with Ubuntu 10.10 Maverick
