I’m looking forward to this being corrected

Although we will be releasing a maintenance shortly (keep your eyes peeled for that) the change we mentioned will be in one of the next upcoming updates.

When you are speaking about UPnP you are speaking about the mapping of the port to the router via UPnP (just to clarify for other users who might be reading 🙂 )

When the nxserver starts up and it makes the request to the router according to how you’ve set up port-mapping, it can some time before the router responds. In our tests, there were some specific models that can take up to 9 minutes before responding back to the server. In the current version, during this time, the player asks the server to confirm the upnpstatus but the nxserver is still waiting for the router to answer. You will probably see that if you leave the Ports panel open, it will update itself after a few minutes (because the nxserver has received a response from the router).

In the next update we will change this behaviour between server and player. The server will tell the player that the setting is activated (or not) even though it is still waiting for the router to respond. This should remove the need to have to manually change it every time.

We received the output and logs that we requested. Thanks for those.
From that we can see there is a crash of Xorg and looks similar to an issue we saw on version 7 which was related to how X server “goes offscreen”, not caused by the NoMachine software itself.

Just to make sure it indeed is that, can you try disabling the blanking of the screen on the Ubuntu server?
open the NoMachine UI on the remote host -> Settings -> Server -> Security and uncheck the ‘Blank the physical screen when somebody connects’ option.

Also, we see that you have lock screen at disconnection disabled. Confirm that indeed it is (it’s in the same Security panel as above).

Hi, this  happens because NoMachine no longer has accessibility permissions. If you’ve updated from version 7 to version 8 of the NoMachine software, you will need re-enable permissions in the macOS security and privacy section.

Open macOS Settings ->  Security & Privacy -> Privacy and add ‘nxnode’ to the list of applications allowed in the accessibility list. If nxnode is already listed, remove and re-add it.

Please submit the logs as requested.

It would also be a good idea to update to the latest version of NoMachine if you are still on v7.

Edit: Topic about sound is solved. A new topic is required if another issue is found.

Hi,

we are aware of a similar issue and a possible workaround (which will be released in the next available maintenance) is to start the client with the following Terminal command:

DISPLAY=localhost:0.0 open -a NoMachine

Let us know if this helps.

Hi,

it looks like nexexec --auth is timing out. Try extending the timeout in the following key available in the server.cfg file

#
# Set for how long the server will wait for the authentication phase
# to be completed on the system. By default timeout is set to 30
# seconds. Increase this value when the authentication process on
# the system takes longer. This setting applies also to two-factor
# authentication.
#
#AuthorizationTimeout 30

Could you please try reinstalling NoMachine again and  then disabling egl with sudo /usr/NX/bin/nxserver --eglcapture no.

Does this help?

Hi, thanks for taking the time to report this. From the log it seems that you need to install gcc make and headers. Take a look at the article here about USB:

First let’s rule out that it’s not being caused by a setting in NoMachine. Could you could try turning off screen blanking in the NoMachine server settings on the Macbook if it is enabled? Does that make the flickering stop in the NoMachine player window?

If that doesn’t help, then you should bear in mind that closing the lid on Macbooks switches the GPU off as a rule and AFAWK there isn’t a system configuration to keep the mac GPU on with the lid closed.

We are not aware of similar issues on Rocky Linux. Can you send us the logs of the affected machine? And the GDB stack of that process when CPU usage is high?

For the stack:
echo "y" | sudo gdb -p 'pidof nxnode.bin' -ex "thread apply all bt full" -ex "quit" &> gdb_nxnode.bin.log

For the NoMachine logs: https://kb.nomachine.com/DT07S00243

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

I think the next step will be to re-enable hardware decoding and see if the sluggishness comes back. If so, I’ll update with new CPU usage info

Ideally, we would need a screen of the Details tab of the Task Manager. If you reproduce it again, submit that.

Both Android and iOS have symbols which don’t exist in the corresponding X11 maps. That said, the next release will provide some improvements to how keyboard is handled when connecting from mobile devices. Keep your eyes open for that 🙂
