Public bug reported:
The issue appeared since a few days and might be related to
transparency/overlay effects used by gnome shell (or firefox for hw-
accelerated rendering). The screen freezes except of mouse pointer
movement, but the system still reacts on keystrokes.
Recent related updates:
03/19: linux-generic-lts-quantal:amd64 3.5.0.25.32 -> 3.5.0.26.33 (including
image und headers)
03/08: xserver-common:amd64 2:1.11.4-0ubuntu10.11 -> 2:1.11.4-0ubuntu10.12
(common, xephyr, xorg-core)
