Hi, there is a Trouble Report open on this issue: https://kb.nomachine.com/TR08W11510.
A patch is already available, lined up for the next maintenance. If you would like to test it, please reach out to us (either through your User Area or here https://www.nomachine.com/support/report-an-issue) so we can send you the right package to install on your Linux server.
Hi, we need to ask a few questions first to understand your set-up better 🙂
– what NoMachine version is on your Windows client (and which version of Windows)?
– do you know what version is on the NoMachine server, your Linux machine where you are working?
– can you tell us if you are running a virtual desktop session?
– what is the desktop environment you are connecting to where Matlab is running (GNOME, KDE, something else)?
– are you starting the session from the NoMachine Player or are you connecting through the browser (perhaps to the landing pad server that you mention)?Hi, thanks for the follow-up. AR02U01190 does not mention Vulkan so I am not sure which article you are referring to. That article indicates amf-amdgpu-pro with the exact steps to follow.
1. If I install older AMDGPU-Pro drivers (e.g., 19.20 or 20.40) that don’t require vulkan-amdgpu-pro for AMF to initialize VCE, will the latest NoMachine version support hardware encoding (H.264) on my Radeon HD 8330E?
Please install only amf-amdgpu-pro (not vulkan-amdgpu-pro) and follow the steps in the article. I just updated it because AMD website’s link is now different.
2. If the latest NoMachine version is incompatible with these older drivers, what is the latest NoMachine version that supports HW encoding with AMDGPU-Pro 19.20 or 20.40 for my GPU?
It’s not a question of NoMachine version being incompatible. NoMachine v8 and v9 support GPU-accelerated H.264 encoding provided by AMD’s Video Coding Engine (VCE) that uses AMF (Advanced Media Framework) SDK API on the Linux machines having a graphics card that support it, using official drivers from the provider. There are so many system configurations that we’re not able to test, and with all different cards available. We are checking with the latest Ubuntu to see if we can reproduce your issue.
3. Are there specific configuration steps (e.g., in /usr/NX/etc/node.cfg) or workarounds (e.g., using VAAPI) to enable HW encoding with my setup?
No, there aren’t any specific configuration options.
Any guidance on compatible driver versions, NoMachine versions, or alternative approaches (e.g., VAAPI, software encoding) would be greatly appreciated.
There’s not much we can add. As I mentioned earlier, it’s not about which specific NoMachine build. HW encoding on Linux in general is like a lottery and more than often it’s about finding the Linux distro version which works with your video card and the specific driver version. We’re checking in our own set-ups as I said and will come back to you.
“When you say uninstall “plugins”, what exactly do you mean?”
I mean that you should revert what you did here:
sudo mkdir -p /opt/intel/mediasdk/plugins
sudo ln -s /usr/lib/x86_64-linux-gnu/dri /opt/intel/mediasdk/pluginsand start again following the instructions in our article.
Hi, all sessions with Connected status should still be showing, and we are not aware of issues with
--history. Are you able to send us the logs with debug enabled? You can extract from the server machine using the instructions here: https://kb.nomachine.com/DT08U00298#1.1.Hi, we are not able to reproduce this. Can you send us the full process list:
$ ps -efAlso the output of loginctl so we can see the parameters of systemd session with type ‘x11’ (or for all sessions). To do this, first list all systemd sessions:
$ loginctl list-sessionsThen, for each systemd session:
$ loginctl show-session <id>If you want to connect just over LAN, you can connect using the IP address of the target computer. You use the Machine Id of the target host if it doesn’t have a public IP address or is behind NAT. In the latter case, you will need to create a NoMachine account and login on the Player before starting your connection. When connecting with the IP address, you don’t need to.
Hi,
there are some instructions for setting up with Intel, so take a look this article https://kb.nomachine.com/AR09O00938. Uninstall all the plugins you have already tried and start again using the article. Does that help?
Hi, first you need to set up NoMachine software for your headless RPi server. NoMachine installs out-of-the-box, however, we have an article that includes some further tips and observations about headless Linux which you can read about in the following article: https://kb.nomachine.com/AR03P00973.
After you’ve installed the NoMachine on your RPi and the server is up and running, you can then add it to NoMachine Network. To do that go to Settings -> Network -> Machine -> Add. This generates a Machine Id and an Access Id. You don’t need a NoMachine account to do that. You basically install, proceed to Settings as mentioned and Add.
Now go to the device you want to connect from. Install NoMachine and create a NoMachine account. When creating an account, you get a 7-day Network Evaluation license to try (after that to continue connecting with the Machine Id you need to get a Network Subscription). Login on the Player where it says ‘Login to Network’ and create your first connection. You can do that by simply inserting the Machine Id in the Search field and then clicking Connect to new host….. or you can choose to click the Add button and enter the Machine Id in the Host field. Insert the Access Id when prompted. Insert the system credential of your account on the RPi.
You will find a step-by-step guide on how to connect with NoMachine with and without the Network service here:

https://www.nomachine.com/support/documents/getting-started-with-nomachine-networkHi, can you do a reboot of the Windows machine? After which, enable debug (Settings > Server > Security>scroll to bottom and select debug level, restart the nxserver, reproduce the error, and take new logs? Full instructions for extracting logs using the UI are available here: https://kb.nomachine.com/DT08U00298#1. You can attach everything here or send direct to forum[at]nomachine[dot]com. Thanks!
Hi, we are checking our update servers, so thanks for reporting. To get to the NoMachine 8.18 update, when you see the notification about NoMachine 9, enable/tick the “Don’t ask again for this version” box and then click “Continue update” button. You should then see the notification about NoMachine 8.18 and a sentence that says “You chose to skip the update to NoMachine 9”.
No problem 🙂
[I] assumed at least the windows version would just auto upgrade to the latest version, I’m guessing the built-in updater only upgrades minor versions?
The built-in updater checks for all updates, major or minor. In the case of a major release, so when you have v8 installed and a v9 becomes available, it will first check that you are aligned with all the v8 updates. Then, if you are on the latest v8 update, it will notify you of the v9 availability.
Did you perhaps disable “Automatically check for updates” in Settings > Updates?
Hi, we have a Trouble Report for “Cannot print from Linux to Windows on a shared printer” – https://kb.nomachine.com/TR09V11210. Work has already been done to fix print problems on Windows/Linux client and server components. The fix has been scheduled for the next maintenance.
Hi, for online subscriptions, outbound access to port 443 (HTTPS) has to be allowed on the host where the Workstation is running (more about this is available here https://kb.nomachine.com/AR11U01209). Rest assured that work is already being done to extend proxy support for outbound web connections, currently desktop client connections can be configured to connect through a proxy. Until then, we can provide license files that do not need to be checked online, what we call “offline” or “on-prem” licenses. You will need these also for machines that are not allowed to connect to the internet at all, Our support or sales teams will be happy to provide what you need in place of the license files you need 🙂
Hi, we got the logs but strangely there were no server logs at all. In the nxd log it’s clear that a connection arrives to the server, and then finishes without any error. Maybe the logs from the client side would be useful at this point. Let’s try this way.
On the server side, go to Settings>Server>Security> scroll down to logs, and set the level to Debug. Restarting the server is requested to make change effective.
On the client side, go to Player Settings -> Security and check option ‘Don’t delete log files on exit’.
Connect to reproduce the error and then 1) click ‘Take the logs’ from the message dialog that you see, and then 2) go back to the server host and click ‘Take logs’ from the Settings>Server>Security. Restore log level 6- Standard to avoid verbose logs. Restarting the server is requested to make change effective.
Send everything by email (one attachment for the player logs, one for the server logs). Thanks!
