With regards to the sound issue, check what is indicated in your Windows sound settings. Are you able to change to another audio output? With regards to the no access on Jetson issue, are you not even able to SSH into it? Have you tried rebooting? Rebooting with a monitor attached or HDMI dongle (if you don’t have a monitor)?

Hi,

please tell us:
1) if pointer/cursor grabbing is enabled in the Player.
2) if you’re sending Ctrl+Alt+Del through the shortcuts menu and you’re reaching the Windows security screen (lock, change user, task manager etc)
3) are those two players connected to the same desktop, each one showing a different monitor?

To restore the GUI you just removed, you can run sudo systemctl set-default graphical.target.

You should still be able to connect with NoMachine 🙂 When you say “not able to get a screen”, what do you mean exactly? Did you install NoMachine on Windows, NoMachine on your Jetson and then tried connecting with NoMachine using the Jetson’s IP address? Can you tell us what happens exactly?

What desktop environment is running in Ubuntu? We have an article here with some tips about how to set up your Jetson. Take a look: https://kb.nomachine.com/AR02R01074 and follow the tips there and let us know how you get on.

Try installing using our official tar.gz packages from our website. Manjaro is a distribution we don’t support, but we tested on the fly and can’t reproduce your issue even with Yay What package did you use? There seems to be quite a lot of NX derivatives (which we can’t handle in these forums). We used “1 aur/nomachine 8.11.3-1 (+90 0.40)”

Please also tell us the Desktop Environment. Is it GNOME? XFCE?

Some tips are available at the above link.

It seems the local system is crashing (not nxplayer). Can you send us the system logs (journalctl) and player logs? Please refer to the following document for instructions 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!

You could also try disabling hardware decoding in the meanwhile (setting it to “disabled”, as explained in https://kb.nomachine.com/AR07U01202), just to exclude a possible problem with drivers.

I just noticed a typo in the previous command I wrote, apologies for that. It should have been

sudo sed -i '' -e 's/^AcceptedAuthenticationMethods.*/AcceptedAuthenticationMethods NX-private-key/' "/Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg"

[Britgirl]

Please check that you actually have sudo privileges.

Open a terminal and from CLI try to edit the file, for example with vim:

sudo vim /Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg

or just use command:

sudo sed -i '' -e 's/^AcceptedAuthenticationMethods.*/AcceptedAuthenticationMethods NX-private-keytest/' "/Applications/NoMachine.app/Contents/Frameworks/etc/server.cfg"

This will change the key to:

AcceptedAuthenticationMethods NX-private-key

It’s still not clear to us what problem with the NoMachine software you are experiencing. The screenshot you attached indicates that the web server doesn’t exist, not that NoMachine is unavailable/not running. You say that this NoMachine server is installed on a dedicated machine via your cloud provider, are you able to SSH into your VM?

Hi, it sounds like a permissions issue with screen recording in macOS. Can you try re-enabling screen recording in the MacBook settings? See the following article for the steps to take: https://kb.nomachine.com/AR11Q01061

If NoMachine has already been added, please remove it and add again.

[Britgirl]

Hi, if the issue happens again, we would like to see the nxtrace. The nxtrace.log file is generated only in case of a sudden termination of any of the NoMachine programs. It’s stored in: %PROGRAMDATA%/NoMachine/var/log on Windows Vista, 7, 8, 8.1, 10. I’ve passed your suggestion on to the developers 🙂

Hi, thanks for letting us know know. If you also tried ‘Scale to window’ mode instead of ‘viewport’ and that didn’t help, it could be related to the GPU on your Linux host that makes available only one resolution when the monitor is not present. A dongle “tricks” the system into thinking the monitor is attached.

It’s one of the workarounds for connecting to headless hosts. See our article in the KB for reference:

Hi, can you send us the server side logs of that Intel machine? We just acquired one of those Intel machines and are also testing it, so we can advise better. It would be good to compare.

These are the instructions for the logs, send them to forum[at]nomachine[dot]com with the title of this topic as the subject of your email 🙂 https://kb.nomachine.com/DT07S00243

Default settings are to not terminate, kill or remove any session that a user initiates. Please check what you have for the following server keys.

#
# Allow NX Server to terminate oldest disconnected sessions:
#
# 1: Enabled. Enable the automatic kill of the disconnected
# sessions.
#
# 0: Disabled. Disconnected sessions are never terminated.
#
# When this option is set and the maximum number of concurrent sessions
# has been reached, the server will kill the oldest disconnected sessions to
# make room for the new session.
#
#EnableAutokillSessions 0

and this:

#
# Set for how long the server has to keep alive virtual desktops in
# status disconnected. When the time is expired, the server will
# terminate virtual desktops if no user are connected there.
#
# 0: Virtual desktops in status disconnected are never terminated.
# This is the default.
#
# >0: Keep Disconnected session alive for this number
# of seconds.
#
#DisconnectedSessionExpiry 0

If they are both set to zero, tell us what NoMachine product and version you are using.

Hi, can you contact us directly at forum[at]nomachine.com and we will send you an apk package to sideload 🙂

We tested on the fly and can’t reproduce. With activegrab enabled, the Windows+3 keys are intercepted and show us the 3rd application running on the remote desktop. In our case, it’s the file explorer.

Can you start the player from a terminal instead like this?
/usr/NX/bin/nxplayer --activegrab
