I just got a second monitor so I can have dual screens on my desktop computer. Upgrading to 12.04, using BIOS to set my main graphic processor to "onboard", and changing the nvidia x server settings to the "seperate x screen" configuration, I was able to succeed in getting Dual Monitors, which I am very proud to have accomplished. The sacrifice seems to have been that I lost some of the cool effects of the sliders, [alt]+[tab] changer looks like windows 95, the workspace changer doesn't work, I cannot access my display preferences outside of the Nvidia X Server. When I go to display preferences, I get this pop-up "Could not get screen information" "RANDR extension is not present". I could be wrong, but it looks like the effects of Unity were disabled when Nvidia took over the Display preferences. How do I return my computer to the fresh look I had when I first installed precise Pangolin and have dual Monitors at the same time?
My main monitor is plugged into my Graphics card expansion listed as NVIDIA Corporation GT218 [GeForce 210], my secondary Monitor is plugged into the VGA port in my Motherboard's I/O Panel which is listed as NVIDIA Corporation C61 [GeForce 7025 / nForce 630a]. I have the accelerated graphics driver "Nvidia accelerated graphics driver (post release updates)(current version updates)" installed.
Here's my Hardware specs from typing
sudo lshw. http://pastebin.ubuntu.com/944869/.
Also I ran
LIBGL_DEBUG=verbose glxinfoand got this: http://pastebin.ubuntu.com/944871/
This is what I got when I entered this command:
lspci -nn | grep VGA
