Hi folks,
We've been having some problems for ages on a Dell bi-pro Xeon Linux box
running FC3 with PCI express and a NVIDIA Quadro FX1300 graphics
board.
We're NOT having the problem on the twin machine, also a Dell bi-pro
Xeon Linux box running FC3, with AGP and NVIDIA Quadro something board
(obviously not the same board, but I forgot what it's called). That one
had been bought 12 months earlier therefore we were not able to purchase
the exact same machine one year later --- unfortunately.
Exactly the same operating system (and version of-) on both machines.
I was next to a user yesterday, who was running ccp4i. Attempt to exit
ccp4i led to monitor extinction (black screen, as when the monitor gets
deactivated after some minutes of inactivity on a
"normal" workstation). Twice I should say, after machine rebooting ccp4i
was launched again and at exit time immediately a black screen.
The X-server cannot be restarted (cntrl-alt-...), init() as root does
nothing, but the cpus are all active and the machine can be accessed
remotely (sftp, ssh). All computations go on normally. It's just the
monitor that is totally unavailable and cannot be woken up.
The same can take place when users go for coffee for too long and come
back to find a black inactive screen.
The company that takes care of the computers has not been able to locate
the cause of the problem (and propose a solution).
We're desperately looking for some information concerning the cause of the
problem and a solution to it (the machine was bought for graphics use in
addition to number crunching, and the graphics part is at the moment quite
useless because of this problem).
Any thoughts, input etc appreciated at this end!
Thanks,
Fred.
