Just posted this to zwaldowski's bug.

For me it's random, actions in all sorts of different applications seem to have triggered it.
- using kubuntu (KDE 4.2) but I think I even had this problem in 3.5...
- The mouse cursor still tracks the mouse.
- Mouse clicks and keyboard input are ignored, requests to change VT are ignored.
- The system itself is still up and running and I can log in remotely via ssh to get things shut down from a full shell. On one occasion this was during a kernel compile and I let that run for another 15 mins AFTER the console freeze, and sure enough it finished correctly.
- Nothing on the display updates, even though there is still clearly activity. eg amarok continues to play until the end of the current track, but amarok's time display stops updating.
- A system shutdown will pause and not close the box down, because it is unable to kill X - I have to intervene with a kill -9. Once I have killed X and stopped the kdm service manually a "poweroff" will work correctly.
- Sometimes a distorted version of the kubuntu shutdown screen appears, sometimes it doesn't.
- If you attempt to restart kdm after killing a dead X, a new X process will run but doesn't appear on the screen. You will also see "[drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck" in syslog.

I am on a MSI Wind / Advent 4211.
