Multi-monitors on client side not working

[chst]

I have a test environment with two linux machines:
One headless server (a linux vm) and a client (bare metal).

Server:
– Debian Bookworm
– nomachine-terminal-server 8.11.3.
– KDE
– lightdm for testing

Client:
– Debian Bookworm
– nomachine-terminal-server 8.11.3.
– xorg
The client has two monitors connected

When testing without NX by starting /usr/lib/xorg/Xorg -query <server ip> on the client I get two screens (xrandr -q) and I’m able to configure them via xrandr or KDE settings. Instead starting /usr/NX/bin/nxplayer on the client I get only the screen ‘nxoutput0’ and the whole desktop is mirrored to the second screen.

When trying to change it within the NoMachine menu panel I could select ‘Resize remote display’ and ‘Fullscreen’ – but there is no button ‘Fullscreen on all monitors’ as described in https://kb.nomachine.com/AR06U01201

Already tried it with ‘Create new virtual desktop’ or ‘Create new custom session’.

Meanwhile I solved the problem:

nxplayer seems not to be able to arrange monitors by itself.
Starting within a full desktop session on the client is no problem if the monitors are already arranged.
But starting nxplayer without any help directly connecting with the X server is not enough.

So I started nxplayer with ‘startx’ and put the following into ‘.xinintrc’ (name of the monitors ‘DP2’ and ‘HDMI2’):

#!/bin/sh
xrandr –output DP2 –primary –output HDMI2 –right-of DP2
exec /usr/NX/bin/nxplayer

Now the button ‘Fullscreen on all monitors’ appears and is working!

And so I didn’t need to install a full desktop environment on the client.
