Hello,
I occurred the same problem, so I installed 2.6.39- 020639rc4- generic #201104191410.
The Unknown display device lost, but with Unity, the dual head screen is broken. The external display is black and the half of lcd laptop is black. I cant see any window in external display.
Maybe log attached will be helpful?
Thanks
