X windows system freezed

[Andrea Giuliano]

I cannot suggest you a solution, but just a test to see what's 
happening. Look at the following quote from a post of mine in a similar 
thread.

Re: Xorg freezes, crashes, locks, shoots and leaves
Dear Gene,

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:

Section "ServerFlags"
    Option        "AllowDeactivateGrabs" "true"
    Option        "AllowClosedownGrabs" "true"
EndSection

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!!!
