Public bug reported:

Binary package hint: unity

When video is playing, and the laptop lid is closed, the graphical
interface stops responding normally. The only way to restore
functionality is to switch to a TTY, kill, and restart Xorg. This
happens no matter how video is played, whether through Totem, VLC, or a
flash player in either Chrome of Friefox. Per power settings, the
computer does not enter a suspend or hibernate mode, when the lid is
closed, but the screen is blanked.

After the lid is opened, the mouse continue to respond normally, but it
is impossible to interact with any interface elements. Any normal
visual-interface key-combinations like alt+tab do not have any effect.
Ctrl+alt+F1 produces a TTY as expected. Killing Xorg is effective, and X
re-launches itself automatically. This issue started immediately after
the upgrade to 11.04, and is consistent and reproducible.
