I use the MATE desktop. I had originally thought I could achieve my
goals using MATE's workspaces.
I found one reference stating explicitly that it cannot be done.
<https://www.datamation.com/open-source/linux-virtual-workspaces-how-do-they-differ.html>
Workspaces in Mate can be individually named, but they share the same
wallpaper and desktop icons with each other.
Therefore I'll change my metaphor.
It is routine for one machine to support multiple independent terminals.
Logically one expect that those terminals could appear on the host device.
How might this be done?
TIA
