Hello,

I hope this can provide more info to help you.
If I can help in any way - like providing more info from tests - just let me know.

I have a lenovo x201 with intel graphics card.
I use an external display at work.

I had Ubuntu 10.10 and the external display was working in an acceptable way (I had to align the external display with the internal by the upper boundary, or I would have problems).

I did the upgrade for 11.04 this weekend (I had some other issues that I was hopping to be fixed with this upgrade).

With 11.04 the two-display solution seems to just don't work.
