I am using the free edition NoMachine_5.2.21_1 (amd64) on both the server and the client machines connecting by NX using private key authentication. As installed from the .deb file, the connection worked fine with a gnome desktop.
Since I needed to create only one session to run a GUI-based server application to be administered via nxclient, I followed the instructions from the KB to create a pre-existing display by editing server.cfg to set …
CreateDisplay 1
DisplayOwner “myuser”
DisplayGeometry “800×600”
but the remote login then gives me Error 111 — I thought it might be the screen geometry so commented out the DisplayGeometry but still could not login via nxclient; I can only login when I set CreateDisplay 0
Is there some trick to setting this up that I might be missing?
