Dual Screens with GeForce 8400GS on Centos 5 issue
 

I've purchased and installed a GeForce 8400GS card into my Centos machine, however I'm having trouble getting dual screens to work.

The card has three outputs VGA, DVI and HDMI (http://www.nvidia.com/object/geforce_8400.html and http://www.outo.co.uk/WebRoot/Store2...S_1GB_DDR3.jpg)

I downloaded the appropriate driver from http://www.nvidia.com/Download/index.aspx?lang=en-us

The one I downloaded was:
Version: 260.19.44 Certified
Release Date: 2011.03.07
Operating System: Linux
Language: English (UK)
File Size: 27.2 MB

I logged in as root and came out of XWindows with init 3 I navigated to the above driver location and did:
sh driver_name.run
The installation all went okay and the DVI connection worked on my main screen after doing init 5 However the VGA and HDMI ports did not work with my secondary monitor, so had a look around and saw the dual dual heads options. I set this up how I expected it to work and after clicking apply, the config was saved so I restarted my machine.
I was then tols that XWindows could not start and it would load a default configuration, which brought up my main screen again in Window mode.

If anyone can offer any advice, I would appreciate it.

Thanks,

Graham

There was a configuration utility that came with the drivers, running that solved the problem
