I suspect this must have been asked before but I cannot find it in the forum, so appologies if it has.

I am using SUSE 10 and I have just upgraded my old and slow nVidia FX-400 to a very nice 6600GT (this one http://www.gigabyte.com.tw/Products/...ProductID=1239 if you are interested).

I had hoped that as both cards were nVidia the process would be relatively problem free but sadly not. Having done the upgrade I can only run in the command line. When I enter 'xload' I get "Error: Cannot open display".

I have updated the nVidia drivers via YOU but that made no difference.

I ran YaST and looked at the hardware settings for the display. BOTH graphics cards (old & new) are listed and both have the same IRQ settings. I suspect this is the root of the problem but how do I resolve it?

The FX-400 was a PCI card (NOT PCI-Express) and the 6600GT is AGP, if that matters?

Personally, I always install the latest nVidia drivers by hand. What I'd suggest is the following:

1. Go to the nVidia driver download page and download the latest Linux driver file. As of today, that's 8178. Note: I'm assuming you still have internet access; if not, use a Live CD such as Knoppix

2. From a terminal session, become root and install the driver. The nVidia page contains instructions on how to do this, but it basically is a simple
A plain text installation procedure will fire up, and the first question it will ask you is to accept the license agreement. Basically you want to just answer "Yes" or "OK" to whatever prompts you get. If you get a message saying that a previous version was detected, remove it

3. During the installation, you might see a warning message or two about the kernel modules, and again just answer "OK" or "Yes" to keep going. If all goes well, it will finish (I'd estimate that it takes about 2 minutes, give or take) and you'll be dropped back out to the prompt.

4. Once it's done, exit root, become your normal user, then startx

That said, and assuming you are familiar with how an xorg.conf file looks (which is what controls your X graphical environment) may still need to manually adjust that file if you still get an error. In my experience, the two most common issues that can prevent X from starting are improper vertical or horizontal sync rates, or that the wrong video driver is specified. For your card, you want the driver to be "nvidia". In any case, let's cross that bridge when we come to it. Good luck with it

I have solved the problem just noticed i didnt have the courtesy to update the thread.

I downloaded the latest drivers but that didn't help. The problem seemed to be that both video cards were still listed in YAST. I tried removing the old one manually but without success. Then after a reboot it mysteriously dissapeared on its own. After that I ran ' sax2 -m 0=nvidia' in the command line as per the following howto:

After that I ran 'startx' and all was well.
