Monitor problems

Hi,

I recently installed nvidia drivers on my SuSE 8.2. Now it works great...I'm playing Warcraft3 with it. But all displays in analogic mode not via digital. I edited XF86Config and set the right tech specifications. I still don't understand how to make DVI to work

When i tried to use DVI something appears i can see the kde desktop, but all is green like HULK

Help

Do someone encounter such kind of problem, my screen displays kde desktop but all becomes very green when i switch to DVI.
I use a 1702FP Dell
on SuSE 8.2

The only thing I could offer is that a hardware fault with the DVI cable may not be connecting the red and blue signals. If not the cable, it could be a problem with the DVI connector on the monitor. Try another cable, or failing that, see if you can take your monitor to a friend's computer (Windows or Linux, it won't matter which) and see if you get a proper picture. If you don't get a proper picture on your friend's computer, the problem is most probably with your monitor. If you do get a good picture there, your monitor and cable are OK, and it's back to the drawing board...

Ok thanks for the info
Is your suggestion true if my monitor works in analog without problems of colours.
The DVI has been working under windows 3 months ago
I will try to relink the cables though...perhaps
Could it be my XF86config file that has a wrong parameter??

Yes, it's possible that your monitor could work in analog mode, but not in DVI mode. One of the possibilities for your colour errors is a hardware problem with the signal not passing correctly through the DVI connector (which I assume is physically different to the analog connector). You've demonstrated that the analog connections are OK; before you go looking for a software problem (another possibility in addition to the DVI connector), you should investigate the possibility for hardware error. It would be so easy for one of the connector pins to not make proper contact. This could be the fault of the cable, or of the DVI connector on your monitor. Manufacturing processes are not perfect; I have personally had a monitor that suffered this particular fault. In my case, the pin in the cable part of the connector was pushed back into the plug, and didn't make contact. A new cable fixed it. It is quite possible that your connections were OK when using it with Windows, but plugging and unplugging has exacerbated a manufacturing fault to cause a poorer connection. Of course, it could be a software configuration fault, but it would be better to rule out the hardware fault first. Troubleshooting is as much about ruling out possibilities on the way to finding the cause as it is about tracking down the cause.
