    Hello: I am connecting to my Linux desktop machine (client 7.7.4) on Macbook Pro Big Sur. When I connect to the Linux desktop NoMachine shows a blank window. How to fix?

    Hi Mark,

    So that we can queue up for investigation, can you please send us server-side logs?

    Please enable debug by executing sudo /etc/NX/nxserver --debug --enable all.
    Then reproduce the problem and collect logs sudo /etc/NX/nxserver --debug --collect

    After collecting the logs you can disable by running sudo /etc/NX/nxserver --debug --disable all

    Please send the logs directly to forum[at]nomachine[dot]com adding the title of the topic to the email subject. Thanks!

    Hi Mark,

    server side logs look clean, so I would need some more information. Is the Linux machine on the login screen when you connect to it? Is it headless (no monitor attached or turned off)? In case it is headless, can you try to attach a monitor and check?

    The Linux Ubuntu 18.04 is in closet I pulled it out and connected a monitor to it. It was on logon screen. I connected to it from my Mac. I had to go back and click on the Ubuntu machine and let it connect.

    So I am halfway there. I need to set up the system so that I do not need to click ‘authorize’ connection on the Ubuntu machine.

    Can it be so configured?

    Okay, I ‘authorized’ the machine by simply pressing the allow other user to control desktop and it stayed set so I dont have to do this. I bought a hdmi headless dongle and that should allow me to go headless.

    Fingers crossed and thank you for your help

    Okay I got the HDMI headless Dongle. Connected it and got black screen..FYI Previously I was connected to USB-C. What is the issue… I am confident if I reconnect my Monitor via USB-C it will all work. What do I need to do to run NoMachine headless?

    OMG – Never heard of headless dongles. I just learned there is also a usb-c headless dongle. I suppose I could connect via HDMI port to the same monitor and use my newly purchased HDMI headless dongle.

    Tips for remote headless Linux hosts are here:

    https://knowledgebase.nomachine.com/AR03P00973 – attaching an HDMI dongle is one of the tips.
