    Hi, I run Manjaro on the server, the client is Windows 10 and when the PC is not connected to a screen I get “Cannot detect any display running. Do you want NoMachine to create a new display” and a blank screen. I have send you the logs in a mail with the topic “Cannot detect any display running. Do you want NoMachine to create a new display”.

    Follow up @graywolf post https://forums.nomachine.com/topic/connection-fails-on-headless-client#post-21783 and in step 2 use those command:

    DefaultDesktopCommand “env DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/$(id -u)/bus /usr/bin/startplasma-x11”
