Hi, Johnny.  Sorry for the delay in answering, but I was trying to make sure 
that I had a fair amount of time to work with the server.

Before I read your message I had the bright idea of seeing what knoppix 
thought about the monitor.  The result was surprising.  Attached is what it 
reported.  I fed that info into xorg.conf and hoped.  Unfortunately I am 
still seeing the blink from time to time, though.

Maybe you are right about the driver not handling the dvi port correctly.  I 
really didn't want to go down the route of the proprietary drivers, so maybe 
I will have to go back to the analogue cable.

I will try your version this morning and let you know whether it helps.  This 
is the last ditch.  If it doesn't help, I'll change the cable back and re-run 
system-config-display.

Thanks again

Anne
