 I've managed to leave the box well alone for a long while, last software
change was when 0.21 was released. Last hardware change was a new power
supply about 8 weeks ago. It was working fine on Friday as I was watching
various recordings. I restarted the box on Saturday morning as it appeared
very unrepsonsive.

My feeling is that some library or such has corrupted. Either that or it's a
graphic card gone bad. It does seem to be whenever X tries to launch an
application such as the frontend or mythwelcome. I've commented out the
lines in the fluxbox conf file which starts mythwelcome, and X is Ok until I
do anything.

I've popped the use events true in the Xorg,conf, and checked that there is
plenty of disk space, even checked that the network is up - I'm stumped.
