When a NoMachine server runs on a machine, it makes a list of network interfaces, and it collects all the information (hostname, list of IPs, ports on which it is listening) and sends it on the LAN where NoMachine clients (on the same LAN) receive this info. This info is used to create an mDNS item in the list. The server cannot know in advance if those IPs are the right ones to use or not. So, if the first of the IPs is “wrong”, the client will fail to connect. What you can do is go in to the Player’s Configuration panel of the connection and check if there are multiple entries in the Host field. An example of what you could see is attached:
Select another item from the list for the connection and then connect.

Hi, I assume your Raspberry is headless. Did you follow the instructions in our tutorial?
https://www.nomachine.com/tips-on-how-to-set-up-your-raspberry-pi-for-remote-access-via-nomachine
See Tip 2: Connecting to a headless Raspberry.
sudo vim /boot/config.txt hdmi_force_hotplug=1 sudo rebootOn RPi4 it’s not required anymore, but on RPi3 it is.
Hi, let me understand better:
1) you’ve been using Xorg (not Wayland) connecting with NoMachine and had no problems up until recently?
2) all of a sudden you’re getting small fonts in the NoMachine player? What have you changed on the host, in the time it was working and when the font problem started? Did you only update NoMachine to 7.10?
2) have you followed your own tips from your original post in https://forums.nomachine.com/topic/no-text-showing-in-client-sceen-under-xorg-kde? e.g reboot?
3) what is the ‘zoom level’ that you mention?
We’ll try and reproduce it here. I’ll write what I wrote last time:
Do the following, open a terminal on the affected host execute ‘xdpyinfo’ and ‘xrdb -query -all’ . What’s the output?
If you change the font in the NoMachine Player settings, does the problem go away?
Hi, this question has already been answered in forums 🙂 Take a look at the following:
https://forums.nomachine.com/topic/disable-ipv6-or-configure-which-interface-to-bindNamely, you can modify the server.cfg to exclude specific addresses

# Specify the network interface where the NX service will be bound.
# Populate the field with an IP address or a domain name.

I’ve gotten it to work just fine across my LAN and over the internet through my firewall.
Great 🙂
From what you’ve written I understand that connecting to a Raspberry device, everything is working well. But when connecting from a Raspberry device or smartphone with the NoMachine mobile app to your Windows 10, you cannot see applications windows. You see only the desktop. Right?
On my Windows 10 Machine it seems to work fine except none of the windows display remotely.
What applications are actually running there? I mean, if I was physically in front of the Windows PC , what applications would be open?
Is the Windows PC with multi-monitors? If so, take a look at this tutorial: https://www.nomachine.com/switching-the-view-between-multi-monitors-during-a-remote-desktop-session.
Hi, take a look at this article in our knowledge base 🙂
How to start the session by passing options to the client from command line
https://kb.nomachine.com/AR02P00963This means that EGL capturing isn’t enabled.
Tell us the output of
sudo /etc/NX/nxserver --egl-capture yesPlease also attach the modified scripts mentioned in the output of the command above.
Also, what is the output of
getcap /usr/bin/gnome-shell?The logs show that physical desktop sharing is disabled for user djoo.
Try running:
sudo /etc/NX/nxserver --useredit djoo --screensharing yes.Just to clarify a small detail. When you mention NoMachine session, which is on Ubuntu, knowing which desktop environment you are connecting to is useful for us. By “desktop environment” I mean KDE, Gnome or any other. OK, thanks for letting us know that the problem is solved. If it happens again, by all means open a support enquiry.
Hi, it’s strange that after 1.5 years of working perfectly that your NoMachine server suddenly starts doing strange things 🙂 That can happen if you have changed something on the headless Ubuntu host, like updating it or changing some configuration perhaps?
I (and others) cannot create new sessions on the server.
What desktop environment are you trying to connect to? Does this mean that you can reconnect sessions already created before the problem started, and that it’s only new sessions which are not possible?
I noticed from the logs that you are running a licensed Small Business Server. This means that you are entitled to receive technical assistance from our support team. Since the forums are public, it might be better to open a ticket and have our support team investigate directly. This will also avoid any sensitive information being accidentally published here. Full debug logs will be required, the ones you sent to us don’t appear to be the full set.
We’ll check this out, but in the meantime, can you tell us the result of the command:
sudo netstat -anlp | grep eglFirst you need to tell NoMachine which printer to use. What you have to do is add the printer you want to use from within the session (whether it’s the default printer or not on the computer you are connecting to or from).
See here:
https://kb.nomachine.com/DT10R00167
If you have an open document in the remote session, you will be able to print it on your local printer. Likewise, if you have a document open on your local desktop, you can send it to the remote printer (server-side) for printing provided you have a connection open.
Step 1 – Click on Connect a printer
Step 2 – Select from the available printers (Fig. 8)
Step 3 – Click ‘Import/Export this printer at session start-up’ if you want this to be available each time you run the remote session. Check the box ‘Make this the default printer’ if required
Step 4 – Click Connect, and wait for a green dot to light up next to your selected printer
Step 5 – Click the back button to close the menu
Hi Dennis,
we are not aware of problems with private key authentication using NX protocol. You’ve mentioned ssh protocol and I am not sure from what you’ve written if this means you’ve tried to run an SSH connection to connect to the NoMachine server from the NoMachine player. Connections via SSH protocol are not possible with the free version of NoMachine, just to be clear.
Can you tell us the version of openssh which you used to generate the RSA key? macOS version and Linux distro and version will also be helpful so we can try and reproduce here. Also useful will be screenshots of what how you have configured the NoMachine connection file (in the Configuration panel of the Add/Edit of the connection you are using).
