NoMachine does not install any DE. A desktop environment is a requirement of being able to get a functional NoMachine installation. NoMachine is designed to work out-of-the-box on Linux headless machines provided a desktop environment is installed. NoMachine is able to detect when the X server is not running and run its own virtual display, which is an embedded X server.
Please consult https://kb.nomachine.com/AR03P00973 for more information on how to use NoMachine on a headless Linux 🙂
Connections via SSH are only available in the Enterprise products. As I suggested, take a look at Enterprise Desktop Evaluation.
Can you tell us which specific notifications are not showing in the NoMachine session but are showing on the physical macOS desktop? Some screenshots would be useful.
We aren’t aware of any of the issues that you described on the supported distributions and desktop environments. Can you tell us what distro you are using and what DE is installed there? What is set in the DefaultDesktopCommand key in the node.cfg on the server?
What you can do is run:
grep ^Exec /usr/share/xsessions/* in a terminal and then use the output as the argument in the node.cfg DefaultDesktopCommand key as explained here: https://kb.nomachine.com/AR04K00667#2 (2. How to run a non-default virtual desktop environment).Can you tell us the exact message that appears when you try to start a NoMachine session to the server? A screenshot of the dialog maybe. Also, the logs that you gathered from the server would be useful.
Hi, SSH connections are available in the Enterprise products. If you have installed Free Edition on the server side, consider installing, instead NoMachine Enterprise Desktop Evaluation.
You can compare the two products here: https://www.nomachine.com/remote-access-for-everybody.
The dump shows a crash of the hardware decoder, possibly related to the drivers. You could try disabling HW decoding. You can try first via the NoMachine Connection Menu (Ctrl-Alt-0 -> Display -> Advanced -> Disable client side hardware decoding) if you’re able to start the session and open the menu. Otherwise,locate the player.cfg on the Linux client and change the follow key <option key=”Enable hardware accelerated decoding” value=”disabled” />. Before changing the configuration key, you should first quit the NoMachine Player (you can do this by right clicking on the !M icon in the system tray and selecting ‘Quit NoMachine Player’).
Thanks for posting. We also found our own workaround that works with a headless set-up.
1. disable xserver
sudo init 3
2. edit /usr/NX/etc/node.cfg and set:
DefaultDesktopCommand "/usr/bin/startfluxbox"
3. restart nxserver
sudo /etc/NX/nxserver --restartWhat macOS is it on the MacBook and what desktop enviroment is on Ubuntu? Do you have two monitors on the macOS side? Is it possible for you to submit a short recording showing the problem?
Thanks for reporting. This needs further investigation and to do so we are trying to get access to the latest PAM authentication agent for Centos 9f from RSA. In the meantime, could you tell us if with SSH everything is working?
This topic might be better investigated via a support ticket if you have a subscription.
Fritz, dragging folders is not supported. You can drag single and multiple files and they will be dropped on to the desktop.
Logs with debug enabled would be useful. Could you try uninstalling completely (removing all traces including the user’s home) and then reinstalling? If you still encounter the problem, then follow the instructions here and resubmit the logs from the server.

Thanks.
We’ll need logs from the server (C-../session logs specifically which are from the agent), this is the easiest way to check what’s happening.
Please follow the instructions here: https://kb.nomachine.com/DT07S00243
