    I’m trying to connect from one Linux machine (Arch Linux) to another Linux machine (Ubuntu 20.04 with XMonad as the window manager). When I try to connect I get the error “Cannot detect any display running. Do you want NoMachine to create a new display and proceed to connect to the desktop?”

    But as far as I’m aware, X server *is* running on the Ubuntu machine. If I click “yes” to the option to create a new display, then it logs into Gnome on the target machine, so I’m running two disconnected X servers. But obviously I want it to connect to the X instance which is already running, where Xmonad is running.

    If I run Gnome on the target machine instead of XMonad, then the NoMachine client can detect the display running and connect with no problems. Xmonad is just a window manager, not a fully-fledged desktop environment, so I’m wondering if there’s something provided by Gnome which is required for the NoMachine client to connect that I’m not getting in XMonad. If so, what?

    Or is there some other issue? All help gratefully received.

    I have to be honest and say that we haven’t tested NoMachine with XMonad. Are you able to send us the server logs from the session? See here for instructions and then send them to forum[at]nomachine[dot]com. Make sure you put the title of this topic as the subject.

    Apologies for not including  the link to the document about logs. I have edited my reply for completeness. Thanks for your logs. We did manage to reproduce the problem and a fix will be released in one of the next software updates. Unfortunately, there is no workaround right now.

    I’m not sure whether it will make the next release which has already been planned.
