Stuck on “Desktop not shared” after updating to 8.13.1

[maRT_sk]

Hello,

I am experiencing an issue with NoMachine on Ubuntu after updating from version 8.11.3 to 8.13.1. I am trying to connect from my Windows 11 PC to my physical Ubuntu 22.04 laptop.

There should be an option available to enable desktop sharing, as shown in the documentation below:

I cannot change this option, so I cannot enable it and it is stuck on “Desktop is not shared.”. I have never faced any connection issues before this update.

Troubleshooting Steps Taken:

Reinstalled NoMachine: I have uninstalled and reinstalled NoMachine several times, but the issue persists.

Modified Configuration Files: I have modified some values in /usr/NX/etc/node.cfg in an attempt to resolve the issue, but without success.

Tried to Enable nxnode: Attempted to manually start the nxnode service without success. The service remains disabled. Checked Service Status: When I run /etc/NX/nxserver –status, I receive the following output:

NX> 111 New connections to NoMachine server are enabled.

NX> 161 Enabled service: nxserver.

NX> 162 Disabled service: nxnode.

NX> 161 Enabled service: nxd.

 

Checked Logs: Here are some log entries:

I would appreciate any guidance on how to resolve this issue and re-enable desktop sharing.

Thank you in advance for your help!

Hi, just to confirm that we understand the issue, do you mean that on your NoMachine Ubuntu host, you cannot see the small “Shared/Not shared” window at all or you see it but cannot change it?

[maRT_sk]

On the host, the option to change from “Desktop not shared” to “Desktop shared”  is not displayed, and I am stuck with “Desktop not shared” – I cannot change it because I do not see the other option.

On the client, I receive the following message when attempting to connect to the host:

Cannot detect any display running. Do you want NoMachine to create a new display and proceed to connect to the desktop?

Previously, NoMachine would automatically connect me to my Ubuntu desktop, allowing me to control my physical machine.

We need to see logs from the affected Ubuntu host.

Please enable debug, restart nxserver, connect and then collect logs (using the command sudo /etc/NX/nxserver --debug --collect). Full instructions are available 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!

Edit 10/10/24: We have received no logs so cannot investigate. We suggest to uninstall completely and re-install NoMachine (the latest version is 8.14) and open a new topic if you have any issues.
