I haven't tried switching users, but I'll test it and report on the BZ
page if I get the problem.

I've also had a strange issue a couple of times where the mouse cursor
disappears. The mouse itself is still active (I can highlight links on
web pages etc., right-click to get a menu, etc.), but then a dialogue
pops up in the top left corner telling me that a monitor has been
disconnected and asking if I want to reconfigure. However this may be
unrelated to the other problem, it's hard to tell.
