Same problem here, I have a Intel X3100 Graphics Card. In this page:
http://ubuntuguide.net/ubuntu-11-04-upgrade-linux-kernel-to-2-6-39-0 They say that the linux kernel should be upgraded from 2.6.38-8 to 2.6.39.0 to solve the problem. Is it advisable to make the upgrade? Or is it better to wait for the automatic upgrade?
