Hi, welcome to our Forums!

What NoMachine counts is the incoming connections on the host (or “server”), not the outgoing connections on the clients. So you are correct in your assumption 🙂 You can start as many connections as you want from any of your machines, but the server computer you want to connect to must have a NoMachine product that lets multiple connections in, if 1 connection is not enough.

So, you say that you want to connect to the Mac from both Windows PCs at the same time. On the Mac you need Enterprise Desktop. On your Windows PCs, you can stick with NoMachine (free version) or simply opt for Enterprise Client if you don’t want the NoMachine server component installed. That’s entirely up to you. To install Enterprise Desktop, you need to uninstall the free NoMachine package.

If I nomachine into a system, can I launch virtual displays to simulate a “multi-monitor” setup on that machine I’m remoting into? Would this let me have two NoMachine windows on PC A into the Mac, one NoMachine window for each monitor on the mac in view at the same time on PC A? because it sounds like that’s possible with the enterprise license features but let me know if I’ve misunderstood, thank you!

Creating “virtual displays”, what we call virtual desktops, is a feature of the NoMachine for Linux products.  On Mac and Windows you get access to the physical display running on the system, it’s not possible to create virtual displays.

You hint at multi-monitors. There can be multi-monitors on the server side so that when you connect to the Mac in the current NoMachine version, you can switch between the monitors (see more about this here: https://www.nomachine.com/switching-the-view-between-multi-monitors-during-a-remote-desktop-session). But you will have one NoMachine window. However, if I understand what you would like to achieve, you might be interested in about a planned feature that will let you display each remote monitor on the server in a separate window on the client side. So you will be able to have one NoMachine window for each monitor attached to the server.

Is there no way to get hardware encoding working with 2560×1440 dual screen setup?

It’s an nvidia limitation, I’m afraid. You can either disable one the monitors or use the option you already tried which is to resize both of them to 1920.

Hardware encoding is not enabled because NVENC, the Nvidia hardware encoder, doesn’t support resolutions over 4K for H.264 hardware encoding. In your logs we can see the following “Info: Remote desktop resized to 5120×1440”. So that is the reason for hardware encoding not being possible.

As for hardware decoding, the resolution limit should be larger but there are no errors in the logs about decoding. Can you check if it’s disabled in the Display settings? Open the session menu (Ctrl-Alt-0) -> Display -> Settings and tell us what you see there (or submit a screenshot). Does hardware decoding work if you resize the remote desktop to a lower resolution?

Are these the logs taken from Ubuntu machine you are connecting to (the remote server)?

[Britgirl]

This is dealt with in the following topic: https://forum.nomachine.com/topic/no-gpu-hardware-encoding.

Logs should be sent to forum[at]nomachine[dot]com. That way we can verify if the drivers are the cause.

Hi, can you submit server side logs so that we can check if it is indeed that TR? You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243

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

[Britgirl]

We aren’t aware of similar problems.

Please tell us:

1) Linux distro running on the server
2) desktop environment you are connecting to
3) OS version on the client side
4) name of the application you are using

Hi,  logs would be useful from both Mac and Ubuntu sides.  You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243

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

Try downgrading to an earlier version of the nvidia drivers. A similar report is here:

NoMachine not using GPU for encoding

The Trouble Report for tracking this issue is the following: https://kb.nomachine.com/TR05V11159

Try adding "/usr/NX/bin" to PATH, not "/usr/NX/bin/nxplayer"

[Britgirl]

For the first point, you’re right. So we are going to implement a new key which will allow you to set the keyboard for virtual sessions when there is no physical display present. For example, it could be something like this #DisplayKeyboard “us”.

Try with a policy kit rule like this:
1) Create the file /etc/polkit-1/rules.d/50-nomachine.rules (as root).
2) Then the rule

polkit.addRule(function(action, subject) {polkit.log(action + ", " + subject);if (~["org.freedesktop.login1.power-off","org.freedesktop.login1.power-off-multiple-sessions","org.freedesktop.login1.reboot","org.freedesktop.login1.reboot-multiple-sessions"].indexOf(action.id)) {return polkit.Result.YES;}});

Can you submit your image as an attachment please (it’s not possible to paste images in to the field for text). Thank you.

First you need to enable VirtualGL which is required so that you can view OpenGL accelerated applications. There is an article in our knowledge base with instructions and tips on how to set up your NoMachine server to use VirtualGL.

It’s a good idea to update to the latest version if possible as well.

[Britgirl]

So now that you have updated to version 8 on both sides (client and server), you get sound?
