Logic aside, I have watched it carefully while I was working there this morning, and it blinked occasionally when I was not touching either keyboard or mouse. OTOH, it could be a sort of ping to the transmitter, I suppose, but if it were that I'd expect a regular pattern. I'll try the old PS/2 keyboard and mouse next time I have a longish session with the server. If I get any likely answers I'll let you know. Thanks for the help.

Comparing your scripts with what I'd actually put into xorg.conf, there were some extra modelins from knoppix, but the only real difference was that I'd put the dri section in. I thought it unlikely that this affect it, but I've taken it out anyway. It still is blinking. If knoppix works perfectly and does not ever blink, then I would say it is a problem with the nv Xorg driver in centos-5. If knoppix also sometimes messes up .. still might be a nv driver issue that is common to both OSes. The proprietary nvidia driver might fix that, it also adds much better 3D performance if you are using that. The modeline stuff with the CentOS-5 nv driver might also make it work correctly, if we were able to exactly define the 14 modes that I saw the monitor supported from your initial sheet. I have to admit that I am not an expert on constructing these modeline settings, but google probably can explain exactly how to construct them. Found this: http://xtiming.sourceforge.net But if the analog cable works OK, that might be the easiest option. One last thought. I did install a wireless mouse and keyboard at the same time as the dvi cable. I have a feeling that the blinking tends to happen when I move the cursor with the mouse. Is it possible that there is interference from the mouse? I have never heard of this happening before, but it would be theoretically possible, though not probable IMHO.

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.

That writes an xorg.conf with no monitor lines at all, then gives you the option of Generic CRT or Generic LCD. I chose the right resolution f rom the LCD list and re-started X.
