Thanks for the link https://kb.nomachine.com/AR08N00898!
The hint about the ‘DefaultDesktopCommand’ was the solution:

I changed it from the default

env -u WAYLAND_DISPLAY /usr/bin/dbus-launch --sh-syntax --exit-with-session /usr/bin/startplasma-x11

to

/usr/bin/startplasma-x11

Now starting a session with ‘Create a new virtual desktop’ instead of ‘Create a new custom session’ works, too.

Interesting detail I’ve learned:
When starting with ‘Create a new custom session’ the option ‘Run the default x client script on the server’ didn’t use the command of ‘DefaultDesktopCommand’ from node.cfg!

Somehow the screenshot has disappeared in my last post.

The following error message appears:

Ooop’s The session negotiation failed
Error: Unexpected program termination.

‘session’ on client:
…

Hello,

I don’t know why but I’m not able to start a virtual desktop.
After about 2 seconds I always get (message/image missing)

But meanwhile I’ve solved the problem with audio:
After disabling pulseaudio in systemd with ‘sudo systemctl –global disable pulseaudio‘ for all users audio was working without problems!

The reason it didn’t worked before seems to be that systemd is starting pulseaudio for users to early.
So restarting pulseaudio within a session works, too.
But I think it should be started by session management of NX.

Looking at ‘systemctl status pulseaudio‘ before and after restart offers the difference:
Before it was listening at ‘/var/run/users/…/pulse/native’ and after restart at ‘.nx/nxdevice/…/audio/native.socket’.

I think this is perhaps only a systemd/Debian related problem.

Best regards,

Chris

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.
