I have two monitors on my PC, the first one connected by VGA and the second one connected using DVI-D. I just bought a new monitor which only allows VGA connection, so i bought a DVI-D to VGA converter in order to connect it as second monitor. However the DVI-D is not recognizing the connection so when i use xrandr to explore connected devices I only obtain the VGA connected monitor.

I am using the graphic device included in the motherboard (Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller). And this is the output that I obtain when using xrandr with the old monitor connected to DVI output:

Screen 0: minimum 8 x 8, current 3200 x 1080, maximum 32767 x 32767

VIRTUAL1 disconnected (normal left inverted right x axis y axis)

It's extrange because it should be using the VIRTUAL1 and not the HDMI1 no? Shall i buy a new DVI-D to VGA converter or it's a configuration problem?

Thank you

P.S: Ubuntu 16.04 LTS

    Replace the converter.

Check your converter. If there is no bulky conversion area (aside from normal sized heads), it is probably a fake cable, especially if bought off eBay.

This is because the digital (DVI-D) signal cannot be just 'rewired' into an analog signal (VGA), and instead must be converted using circuitry.
