    Hello everyone,

    I would like to see if you can help me. I’m trying to connect to a remote desktop server with NoMachine. My operating system is Ubuntu 23.10.
    I manage to connect, but when loading my virtual desktop I have a serious refresh problem that doesn’t let me work at all. If I connect to the physical desktop it disconnects me directly. I have seen that the refresh is at 60fps. I’m not sure what to do.



    please tell us:

    – NoMachine version and product on both client and server sides
    – OS on client side
    – Linux desktop environment on Ubuntu server side
    – What message you see when you try to connect to the physical desktop
    – Follow the tips here:


    NoMachine  client Version: 8.11.3, Linux

    NoMachine  server Version: 8.8.1 con player 8.11.3 , Linux

    OS client:

    – Ubuntu 23.10

    – GNOME Shell 45.2

    I don’t receive any error message. It just doesn’t work, you can’t work given the latency. The delay is brutal and does not refresh the graphics properly in real time.


    In fact your session stats show that latency is indeed the problem, 1106 ms latency 5s, 840 ms latency 30s with regards to your network. So check your network 😉

    Did you follow the tips in the article I referred you to in my previous reply, it’s about headless Linux machines. Is your Ubuntu headless?

    Please clarify the problem you are experiencing when connecting to the physical display. In your first message you said that you “get disconnected directly”.

    Logs from the server would be useful. You can extract them using the instructions here:

    Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!
