Video Accelerator doesn't support Dual Monitor
 

I need to install a video accelerator on Ubuntu 12.04. The ONLY problem I'm having is that every time I install it, my dual monitors don't working anymore.

I would just leave it alone and not install it, but I can't play videos from the default player and I can't upload videos to Youtube. My computer already supports OpenGL and everything.

Any suggestions?

what kind of os and video you have? Which driver have you tried?

I'm using Ubuntu 12.04. I have tried the NVIDIA accelerator graphics driver (version current)[Recommended] and the NVIDIA accelerator graphics driver (post-release updates)[version current-updates] I'm not sure what video I'm using. Can you tell me how to find that out?

To find out which graphics card you use:Not related to the video card at all.

Have you tried to configure your monitors with Nvidia's configuration tool?

I have 64-bit OS. Graphics are: GeForce 8800 GTS 512/PCIe/SSE2 And I will try Nvidia's configuration next! How to I get to the configuration tool

I've gotten both monitors to work now. Everything is fine, expect that the OpenGL stuff doesn't work.

Please post exactly what you are trying to do and which error-messages you get.
