Probably not a "mouse" hangup but a proper crash. The fact that you
mention everything is frozen means this is not a mouse problem.

First of all, don't do a hard shutdown.
hit magic key (alt-SysRq) and enter REISUB to safely restart your PC.

(and many more on Google for details).

Most likely even doing Alt-SysRq-R is enough to be able to do a
CTRL-ALT-F1, if X11 is the problem. If not at least you'll not be
trashing your file system eventually.
