Your system has the GeForce GTX 680 GPU. The latest nvidia driver to support that GPU is the 470xx driver from rpmfusion. You seem to be using the default nouveau driver.

The second GPU shows as a Matrox Systems MGA G200eW WPCM450.
According you your post this seems the important info

The last line there is important. disabled as is the overall resolution 2944x1080

  1. What happens if you go into the settings → display panel and select mirrored for the displays?
  2. Is one of the monitors disabled in that panel?

The monitor is clearly being recognized but is being disabled by some setting.

Hi Jeff, Thank you for the analysis and suggestions. I could not find the display panel. i was trying it earlier as well. i searched for it in the settings to check for the monitor display but could not find it . It need to be installed separately ?

No, Simply right click on the background area of the desktop screen and it should open up a menu with 3 options. (change background, display settings, settings)

You can also open up the settings panel from the icons at the top right of the screen toolbar.

Dear jeff,
Thank you very much. I was able to check the display by right click. i just checked with the HDMI cable instead of DVI and second monitor is recognized only by HDMI. If i plug in DVI it disapears and comes back when connected through HDMI
