OpenSUSE Tumbleweed – ERROR! Limit of 1 virtual sessions has been reached

[CRCinAU]

I’ve done a fresh install of OpenSUSE Tumbleweed – and then first thing I start doing is to install NoMachine.

I installed: nomachine_9.2.18_3_x86_64.rpm

In my configuration, I set the following in server.cfg:
DisablePersistentSession “all”
EnableNetworkBroadcast 0
CreateDisplay 1
DisplayOwner “myusername”

In node.cfg, I set:
DefaultDesktopCommand “dbus-launch –exit-with-session /usr/bin/startplasma-x11”

The connection fails, and in server.log, I get the following errors:

Info: Handler started with pid 7527 on Tue Nov 11 23:57:41 2025.

Info: Handling connection from port 48802 on Tue Nov 11 23:57:41 2025.

Anyone come across this before? It’s a new one for me…

It seems like the dbus-daemon is missing. Try manually installing the package dbus-1-daemon. Once installed, dbus-launch can properly start a D-Bus session, and the KDE virtual desktop session should start successfully. The command to install dbus-1-daemon by zypper is “sudo zypper install dbus-1-daemon”. Does that help?
