Question How can I share my secondary monitor to a remote system as if it were directly connected to it?

[Manuel Jordan]

Introduction

A laptop typically has either a VGA or HDMI connector as a display port, and some laptops even have both. If you connect a secondary monitor to this laptop, you can easily drag and drop any window from the primary to the secondary monitor and work seamlessly.

This functionality applies to all workspaces as well.

Situation

Through Remmina is possible get remote access from a Host laptop to a target laptop - for simplicity it in the same LAN - in peace. The situation is that the target laptop does not have a secondary monitor and the host laptop has a secondary monitor. Therefore:

Host Laptop (1 Secondary Monitor) >>> --- --- Remmina --- --->>> Target Laptop (0 Secondary Monitor)

Goal

I want need to know if is possible execute a command in the target laptop to cheat the OS to indicate that it has connected a secondary monitor based on the same settings than the one connected in the Host laptop. Of course, there is no a secondary monitor connected in the Target Laptop.

Therefore the "fake" scenario should be the same as if exists two identical displays/monitors and each one is connected to each laptop. Thus in the Host laptop is possible drag and drop any window to the secondary monitor - it without matter if really the Target monitor does not have a real secondary monitor connected.

Is possible accomplish this goal? I need this command being generic or portable, it to be executed in Ubuntu and Fedora.

no clue in remmina, but its opensourced, so you could add few lines there to make that happen

but since both of your systems are linux based, why dont u just stick with X server? thats the native linux GUI which is actually client-server

is 2 computers "sharing" an X Server possible?

is it possible to have one computer running an X Server and connecting to it and another computer (connected via LAN or something) also connecting so you can run one app on one computer while you can run another on the second. okay so you might think: why would you want to do that? well cluster...

Remmina is just the mode to access the target ... it could be other software, such as TeamViewer

but since both of your systems are linux based

Yes, in this case both are Ubuntu

why dont u just stick with X server? thats the native linux GUI which is actually client-server

Pls, could you expand the idea?, how it would work in the target?
