Aren’t you using gdm? Check where is placed Xsession script.
sudo find /etc -name "Xsession"and use those path in DefaultDesktopCommand. For example:
DefaultDesktopCommand "/etc/X11/xinit/Xsession gnome-session --session=gnome"Hi.
Are those commands are from Fedora 36? Just try this if you have gnome:
DefaultDesktopCommand "/etc/gdm/Xsession gnome-session"We modified a little your script. It works now as you planned. Just create folder:
sudo mkdir -p /usr/NX/scripts/customand place there script, set permissions:
sudo chown nx:nx /usr/NX/scripts/custom/UserScriptBeforeLogin.sh
sudo chmod 755 /usr/NX/scripts/custom/UserScriptBeforeLogin.shand uncomment and edit following key in /usr/NX/etc/server.cfg:
UserScriptBeforeLogin "/usr/NX/scripts/custom/UserScriptBeforeLogin.sh"What audio tool is set on node configuration? To check this please show output of the command:
sudo grep AudioInterface /usr/NX/etc/node.cfgDefault on Ubuntu 22.04 should be set:
AudioInterface pulseaudioIf you have different, please open /usr/NX/etc/node.cfg file and set mention value.
We checked in our labs here, and we have no problem with connections when NordVPN is also running. Did you try the connection to the correct IP? The MDNS port might be blocked so broadcasting host in the network won’t work in the player, but it is still possible to connect using IP address.
Hi
Logs indicate that you are trying to use VirtualGL. There are instructions how to enable it on the NoMachine: https://kb.nomachine.com/AR05P00982. After enabling VirtualGL please set default command in node.cfg:
DefaultDesktopCommand "env XDG_SESSION_TYPE=x11 /bin/dbus-launch --exit-with-session gnome-session --session=gnome"We were able to reproduce the problem on Chromium on physical display (on x.org desktop) without NoMachine which means that this is not a bug in NoMachine.
Hi
It looks like you are trying to connect over the internet to the server host. Port 4000 can be used in local connections, but if you want to use it in the connection from external network – you need to open that port on the router manually. More info about how to connect over internet you can find there: https://kb.nomachine.com/AR10R01099
Hi.
We couldn’t reproduce such problem. What OS is on client side? Which NoMachine version is installed on both sides? What resolution is on server host? Is this connection to the physical desktop? Is there “Resize remote display” option enabled in the player? Did you change some display options in the player during connection?
According to the RPi documentation – dtoverlay option requests the firmware to load a named Device Tree overlay – a configuration file that can enable kernel support for built-in and external hardware (https://www.raspberrypi.com/documentation/computers/configuration.html#part3.1).
Try to set the older driver:
dtoverlay=vc4-fkms-v3d max_framebuffers=2and let us know if you see the difference.
Hello
why can’t I update the NoMachine server on a remote desktop anymore?
It has never been possible to run the software updates in a virtual desktop session. Software updates need to download new files and run the procedure to activate them. Part of this procedure consists in shutting down the nxserver, applying changes, restarting the nxserver. This could not work in a virtual desktop, when shutting down the server the session would be closed and the procedure would break.
On a headless machine the same conditions apply. With no X server running or detected, NoMachine start it’s own virtual display. Updating the nxserver, it must shut down and therefore the session is interrupted.
You can download and update NoMachine via command line with those commands:
wget https://www.nomachine.com/free/linux/64/rpm -O nomachine_7.10.1_1_x86_64.rpm sudo rpm -U nomachine_7.10.1_1_x86_64.rpmEverything you need to know is the following document in our knowledge base which gives multiple examples of what and how to configure specific items of the player.cfg and session file. Please see:

Additional information about storing the password is available here. https://kb.nomachine.com/AR01C00125
This key
<option key="SSH Client" value="/usr/bin/ssh" />can be used to change the path to the native client. So if you want to change the env, you can create a script to do this and then spawn the ssh process by using the path of the script as the value.Hi
First of all close all nxplayer processes with button “Quit NoMachine player” which you can find by clicking on NoMachine icon on the system tray. This is needed to save changes in player.cfg. Configuration file you can find in
~/.nx/config/player.cfg. Key which you are looking for is “SSH client mode”. Change value from “library” to “native”. The line should look like this:<option key="SSH client mode" value="native" />Hi, as you probably read in the article you referenced, NoMachine is able to detect when the X server is not running and run its own virtual display, which is an embedded X server. If you don’t have an integrated graphics card or VGA port, NoMachine cannot detect an X server and thus launches its own “virtual desktop”. If there is a GPU, and so a physical X session is already running, NoMachine doesn’t need to run its own display to launch the desktop environment.
That said, Ubuntu 22.04 doesn’t make available by default the command used by NoMachine to launch the desktop inside our virtual display. We will be making the necessary adjustments in an upcoming software update. In the meantime, please check one of these methods and let us know if it helps:
I) install dbus-x11 package:
sudo apt install dbus-x11II) set /usr/NX/etc/node.cfg key?
DefaultDesktopCommand “dbus-run-session gnome-session --session=ubuntu”
