Hi there,

I have two Ubuntu 18.04 PCs.

They both have graphics cards one a Geforce 1080Ti the other a Geforce 2080Ti.

They are connected to the same two monitors via a TESmart KVM.

As shown in the link above each PC connects to the KVM via one hdmi port and one VGA port.

As neither of the PC's has a VGA port it was necessary to use a VGA to HDMI adaptor for both PCs.

The PC with the 1080Ti card worked straight away, I can use that PC on one or both screens as intended.

The PC with the 2080Ti card will only showing on one screen no matter what I do, I can't seem to get the second screen to work.
I have already updated the GPU drivers but no success.
However it's hard to do much else as when I connect the second computer to the VGA port the top and bottom tool bars disappear see attached pictures. This means I can't go into activities-> screen display to try and see what's going on.





Can someone please explain how to resolve this?

Thanks

Baz
