Dual monitor not detected

Question

I've a desktop computer having Ubuntu 16.04 updated from 14.04 (It wan't working in 14.04 too though). I've two graphic cards on system. They are as follow,

00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2)

I've two monitor attached on two different VGA ports, although only single monitor is detected in System -> Display settings and nVidia Settings.

Drivers for nVidia are up-to-date and working perfectly fine.

Any solutions? Is it Intel and nVidia don't support together on Ubuntu ? (It does work on Windows)

Answer 1

I've solved it by Getting HDMI to VGA converter and using both the displays from single graphics card.

May be Ubuntu doesn't support multiple graphics card to use with dual monitor at once, but using converter solved my issue.
