I have a Lenovo X201 tablet. I just upgraded to Ubuntu 11.04. Now, when I rotate the screen (switching the tablet from laptop to slate mode) sometimes the screen is black and does not show anything any more. The session is still running,
but nothing is displayed ever again. I have tried head from git on the driver, but the problem remains.
The problem happens one out of 3-5 times I rotate, but it random.

Onre more thing, I use xrand to automatically rotate (using acpi to trigger the event):
xrandr -o right
