Failed to load driver Iris error

[theno2soco]

I am using an XPS13-9300 laptop with VirtScreen installed. Using Ubuntu 20.04

I am attempting to use VirtScreen to connect to Samsung Tab A which is running a vnc client. I have installed x11vnc and configured as required.

When I select the VirtServe icon I have menu with 4 options:

1. Enable VirtScreen First
2. Enable Virtual Screen
3. Start VNC Server
4. Open VirtScreen
   Start VNC Server (3) is greyed out. According to the x11vnc icon, it is running.

When I select (4) in the drop down menu VirScreen appears to crash. When I start it again and select entry (1) I get: 'No virtual screen name found' appearing in the icon drop down menu below (1)

The tablet vnc client bVNC Pro fails to connect with VirtScreen, attempting to get a handshake with a long error message.

I am unable to get the gui for VirtScreen to set anything up.
