Ubuntu 9.10 & Nvidia 7600 GT display problems

[shtaffa]

I have a Nvidia 7600GT dual head video card. I enabled the restricted drivers and I have even installed the latest drivers from the Nvidia web page. I am stuck with one display running at 640 X 480.

Suggestions?

Thanks for the link.

I've follow the instructions and kind of have it working. I've been tinkering around with settings either in my xorg.conf and the Nvidia X Server Settings and I can't figure out how to get it working correctly.

In the Nvidia X Server Settings I can now see that there is a second monitor. By default it's disabled. I'm able to enable it, change the position and change the resolution. However, I can only set it to a maximum of 640x480. If I do that and then reboot, it's turned back off.

OK.

So now I can get the nvidia settings to save to xorg.conf. However, I still can't set my second monitor above 640x480.

If I set it as 640x480 and save the settings I can then open up xorg.conf and see the setting changes that I have made. I then manually edit xorg.conf to change the 640x480 to 1400x1050. I then log out, log back in and my second monitor is disabled.

As I sat back and read the messages that I have posted in this thread, I saw that my description of what is happening is not clear.

First off, I have two identical Acer 20" DFP 4:3 displays. Their native resolution is 1400x1050.

After installing the Nvidia drivers I only had one display working with a resolution of 640x480. After following the instructions that tachuela gave me the link to, I now have one display that is running at 1400x1050 and one that is running at 640x480.

If I open the nvidia settings, I am unable to change the resolution of the 640x480 display to anything higher. It is also being recognized as "DFP-0" while the one that is working properly is being recognized as "Acer AL2017 A". I have included a screenshot of the nvidia setting program.

Here is a copy of my xorg.conf:

The commented line regarding the removed metamodes option is a line that I manually edited hoping to set the 640x480 monitor to 1400x1050. After doing that and rebooting the system, the monitor that was formerly running at 640x480 was completely disabled. I was able to go back in to the nvidia settings and change it from a resolution of "none" to 640x480 again. It was once again up and running, but still at 640x480.

Anyone have any idea how I can either get the system to recognize my second monitor or at least get it to work at 1400x1050?
