[K12OSN] sudden apearance of X errors - solved

	server 64 bit Centos 5.6, Ltsp 32 bit 4.x.

Turns out I was chasing my own tail. The problem turned out to be hardware
related, more specifically, network related. A well meaning soul laid his
hands on the key to the attendance hand scanner and to make sure it works
perfectly well changed the address on it to be the same as the eth0
address on the server. People won't tell me who it was.

	I went about finding the solution by first admitting it is not a
software problem and then disconnecting switches from the stack. Once I
got it down to a particular switch I disconnected all the ports and
reconnected them one by one. Culprit was found, but not immediately. What
a pain.

Thank you very much for your support.
