What is the Vulcan Death Grip you ask? It is a sequence of keys, that when pressed simultaneously, reset’s an SGI workstation’s X Windows session. It does not reboot the machine, only restarts the X Windows session. Anybody logged onto this machine from a remote location will be unaffected.
Usually, if a SGI Unix box freezes, this is the first thing to try. If that does no good, you might have to a hard reset to the machine.
XSgi is the program that intercepts this sequence.
