Xorg freezes, crashes, locks, shoots and leaves

I know your problem very well! Anyway, after having X freezing the
system for several months, at present it doesn't happen any more. It's
hard to say way.
I only can suggest you to add the following lines to xorg.conf:
Option "AllowDeactivateGrabs" "true"
Option "AllowClosedownGrabs" "true"
They allow you to use C-A-K-* and C-A-K-/ to try to unlock X in some
situations (see man xorg.conf for a few detail). To avoid
misunderstandings, please note that C-A-K-* means "Control, Alt, Keypad
*" pressed together.
This could be a start to investigate what is happening to your system. I
would not be very optimistic, but at least you can try, it's very easy.
Remember to restart your X server after the changes above.
Best regards... and good luck!!!
