NoMachine stopped working after upgrade to 13.1

[smat70xc]

Hi,

I am on Manjaro Linux machine.  NoMachine was working wonderful over months until upgrade to version 13.1. Since this no connection is possible or more exactly it will be established and very very soon closed again.

I tried to reinstall version 12.12  – it worked previously perfectly but now it’s same as in a new version 13.1

I tried to set

(base) [me@me-qm2 ~]$ sudo cat .nx/config/player.cfg | grep -ni hardware
50:  <option key=”Enable hardware accelerated decoding” value=”disabled” />

as I read in another topics here, but with no success.

In the log file (in very first effort something more, afterwards only few lines repeated over and over as can be seen at the bottom of the  file – starting with the key 2598) I see:

(base) [me@me-qm2 log]$ sudo cat nxserver.log

Any idea what’s wrong and how to get NoMachine to run? Is it something with Redis …

Thanks a lot in advance

Hi smat70xc,

We are not able to reproduce this bug, so your logs would be helpful to understand what goes wrong.

If needed, here’s the procedure to collect NoMachine logs: NoMachine – Collect Server And Client Logs Manually – Knowledge Base

Can you please send them to forum[at]nomachine[dot]com, making sure to reference the topic as the subject of the email?

[smat70xc]

Hi, using NoMachine from my Mac works, but still not if I try to connect from Manjaro ;-(

It works also from Android 😉

[Bilbotine]

Hi smat70xc,

The logs you sent us don’t show anything wrong.

But from your description, it seems that the problem is on the client side on that machine (Manjaro).

Considering this, please check the player side logs (they are in ~/.nx ), and tell us what error it says, etc.

[smat70xc]

Hi Bilbotine,

thanks a lot for your time and the response.

Yesterday and also today I spent few hours trying to understand what’s going wrong.

After connecting from mac, android and also from my machine but under another linux’es it seems that it something tiny in my Manjaro 24.

The log file on the client site on Manjaro 24 delivers no really a hint or maybe I interpret as a problem with PulseAudio and it is not correctly or the consequence of that makes some troubles thought?

I see only many repetitions of a below inserted sequence:

>>>
Connection failure: Connection refused
pa_context_connect() failed: Connection refused
2294 2294 2024-08-30 17:41:15 224.824 NXNODE   WARNING! Process ‘/bin/pactl info’ with pid ‘2310/2310’ finished with exit code 1 after 0,003 seconds.
<<<

For sake of completeness I attach the full nxserver.log from .nx directory.

Have a nice day

Matthias

[smat70xc]

On my another Manjaro machine with similar behavior I can see something more in the client nxserver.log after a try to connect

[Britgirl]

Hi, please submit the logs to forum[at]nomachine[dot]com. I see that the link was not visible in an earlier reply from Bilbotine, so here’s the link.

https://kb.nomachine.com/DT07S00243

Please use the title of this topic as the subject of your email.

[Britgirl]

It’s strange that you can connect from other clients without issues. As you said the problem appears to be on the Manjaro device you are connecting from, so for that we need the Player logs which were missing. See “Fourth Step: Collect Client Side Logs” in the link I gave previously.

[Britgirl]

Thanks for the player logs.

A crash is observed:

18874 18874 2024-09-03 09:26:14 034,814 ClientSignal: WARNING! Child process ‘18979’ died because of signal ’11’, ‘SIGSEGV’.

It would be useful to see a backtrace from the core file/crash report. Please see the instructions here:
https://kb.nomachine.com/AR09L00810

[Britgirl]

You mentioned that you had tried disabling HW decoding, but the crash report indicates that HW decoding is still being loaded. You need to “Quit NoMachine player” before changing it, edit the key to<option key=”Enable hardware accelerated decoding” value=”disabled” /> and save. Open NoMachine and start the session.

Please refer to this article for reference:
