All of the frontends (clients) are identical hardware? If so, are the BIOS
video settings identical in terms of memory size, onboard vs add-on
priority? Sounds like X.Org locking up is the root of your problem. The log
you might want to check is /var/logs/X.org.log from your frontend or
whatever it is named on your distro.
The first change you cite on 05/03/2013 was when the problem started, just
after you changed the network switch? Or that was the remedy you tried
after having had problems with this client.
Cheers,
