Linux – Multiple virtual Monitors in Linux Guest with VMware Workstation 12

linuxmultiple-monitorsvirtual machinevmware-workstation

First off: This question is not about displaying the guest on multiple host monitors.

The goal is to use multiple monitors in the guest OS, independently of the host's display layout.

In fact my PC running VMware Workstation only has one single Monitor.

The background is to conveniently test how a certain Linux software product behaves with multiple and exotic multi-monitor setups without having to create the physical setup.

Using a Windows 7 guest I was simply able to do the following:

VMWare Workstation virtual monitor setup

This image shows a Windows 7 Guest with 3 virtual monitors being displayed in one VMWare Workstation window.

However, I'm unable to duplicate this setup using a Linux guest (in my case Ubunutu 16.10).

The Linux guest machine configuration exactly matches the Windows VM and I can see multiple displays in the xrandr output:

$ xrandr

Virtual3 disconnected (normal left inverted right x axis y axis)
Virtual4 disconnected (normal left inverted right x axis y axis)
Virtual5 disconnected (normal left inverted right x axis y axis)
Virtual6 disconnected (normal left inverted right x axis y axis)
Virtual7 disconnected (normal left inverted right x axis y axis)
Virtual8 disconnected (normal left inverted right x axis y axis)

And also the GUI display settings show only one available display.

How can I connect these disconnected displays?
