Currently the client follows the selected DPI when painting on screen. In the future we are consider implementing an option to ignore the DPI. But this is still being evaluated.

Hi, this is related to the GPU’s capabilities.

Please consult this article from our online knowledge base:

How to solve ‘stuck resolution’ problems on headless machines
https://kb.nomachine.com/AR05S01127

“In some cases users can get only a small screen resolution without the possibility to change it (‘stuck resolution’).  This depends on the GPU which makes available only one resolution when the monitor is not present.

A common solution is to adopt a fake display dongle (also called ‘dummy dongle’) inserted in the video card port to simulate the presence of a screen and force the system to take full advantage of the GPU as if a real monitor is connected.”

I’m not sure what you mean by “Opening the settings on the headless windows machine also doesn’t really work because when I scroll to the desired setting only the scrollbar moves and everything else stays still.” A recording of the NoMachine session would be useful to illustrate the problem perhaps.

Hi,

we’ve just updated an article that will help with configuring your Fedora NoMachine server in an AD domain using the NX protocol.

mcjev, thanks for letting us know.

If you happen to switch back to Wayland and only if you want to, enable the logs on the server side and send them to us so we can check. This would help us understand what’s going on.

See this article for instructions: https://www.nomachine.com/DT11R00182

Thanks for letting us know. We’re checking and will update the topic soon.

I understand that on X.org everything works fine but with Wayland it’s laggy. Could you follow the suggestions in this article?

Connecting to a Wayland-based desktop running in a Linux virtual machine

Look at the sections Option 1 “PipeWire desktop sharing provided by the desktop compositor” and Option 2″Use EGL capture”.

Please also check our notes for recommendations and tips:

If you have the lid closed on the laptop you should stop the graphic interface and use it as a headless machine. The remote session will then work as a virtual session (see this article for futher information: https://kb.nomachine.com/AR03P00973). Then connecting via NoMachine to a headless Linux, it will detect that no display is running and ask you if you want to create one.

If the lid is open, Xorg will work as it should and physical sessions will work correctly.

We’ve not been able to reproduce this problem, despite several attempts. Are you able to send us the logs from the server sideso we can take a look? Please follow the instructions here and send them forum[at]nomachine[dot]com making sure to use the title of your topic as the subject of your email.

We’ve not been able to reproduce this problem on our RPi and with snap, despite several attempts. It could be something to do with a specific setting or configuration in your Oracle VM, is this possible? Are you able to send us the logs from the server sideso we can take a look?

You can install NoMachine on a headless Linux host and connect to its display. I imagine you already using this on your Ubuntu workstation. Some considerations to bear mind:

Connecting to Linux headless machines with NoMachine
https://kb.nomachine.com/AR03P00973

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. This ability, enabled by default in the free edition of NoMachine, can be activated also in the commercial versions (Enterprise Desktop).

If you want to run multiple virtual displays, and keep your applications running in all of them, try NoMachine Workstation from the Terminal Server for Linux suite. This will let you run up to 4 individual desktop sessions, all running behind the physical display. It’s also available as evaluation software.

Please follow the configuration tips for Arch-based installations which are from a separate topic:

https://forums.nomachine.com/topic/help-changing-resolution-on-connection#post-39768

I’ve pasted them here for your convenience

1. Create a backup of nx PAM configuration (sudo cp -a /etc/pam.d/nx /etc/pam.d/nx.original). Then change /etc/pam.d/nx in this way:

auth       include       system-login
account    include       system-login
password   include       system-login
session    include       system-login

2. Change DefaultDesktopCommand in /usr/NX/etc/node.cfg in order to have this on KDE:

DefaultDesktopCommand "/usr/bin/dbus-launch --sh-syntax --exit-with-session /usr/bin/startplasma-x11"

3. Stop display manager:
sudo systemctl stop display-manager

4. Restart NoMachine:
sudo /etc/NX/nxserver --restart

Does the taskbar appear?

Hi,

NoMachine lets you connect to the physical display on the Windows machine i.e it displays an exact copy of the graphics card’s output. Connecting to a virtual display running on the Windows host is not possible. This is available in the NoMachine for Linux products i.e i) NoMachine Free Edition for Linux allows one connection to the physical display of the Linux machine and in the absence of a physical display, NoMachine can create a virtual one; or ii) in NoMachine Linux Terminal Server products which let multiple users connect to their own individual Linux desktop all running on the same machine.

Hi,

if there were a seamless way to allow for both local and remote shortcuts, we would have already implemented it 😉

What you can do is to use Ctrl+Alt+M to minimize the NoMachine session window when in full-screen. Ctrl+Alt+K is also useful to toggle keyboard grabbing on and off, and Ctrl+Alt+0 to opens the NoMachine session menu instead of the page-peel.

But the video drivers for Radeon came up

Hi, do you mean that you’ve updated the drivers?

[Britgirl]

Hello, can you confirm which package you’ve installed? The tar.gz is the most appropriate for Arch Linux, and I would remove and install again just to make sure. We checked recently that NoMachine installs and works with Arch Linux, which it does.

Please do the following, where “nomachine-current-installation-file.tar.gz” is the name of the package you installed.

sudo /usr/NX/scripts/setup/nxserver --uninstall 
sudo rm -r /usr/NX/ /etc/NX
sudo tar zxf nomachine-current-installation-file.tar.gz -C /usr
sudo /usr/NX/nxserver --install redhat
