Can you send us a screenshot of the mac’s “display arrangement” in the Display settings?

Hi, it could be a problem with drivers. Have you tried separate NoMachine sessions for AMD and nvidia cards? What happens?

Can you try disabling hardware decoding on the client side? To do that, please edit the $HOME/.nx/config/player.cfg and change the ‘Enable hardware accelerated decoding’ key to:

option key=”Enable hardware accelerated decoding” value=”disabled” 

What’s the result?

Hi, your last explanation clarifies things a lot It’s not a NoMachine issue, it’s a bug in Gnome and is reported on other forums also with other remote desktop tools. You can unlock it by staring starting an ssh terminal to the host as the same username and run the following:

loginctl unlock-sessions

We also suggest to disable automatic screen lock on that machine.

Hi, it’s certainly not something we’ve seen during tests and very unusual. We’re not quite sure how NoMachine client hanging could be related to high throughput on the affected device, so logs from the affected client Linux device would be useful in this case.

You should make sure the check box “Don’t delete logs on exit” is ticked in the Player settings -> Security panel, and then reproduce the problem. Detailed instructions on how to gather the client-side logs are available here: https://kb.nomachine.com/DT11R00181#2. Please send them directly to forum[at]nomachine[dot]com making sure to reference the topic title in the subject of your email. Thanks!

Hi, this is supported in traditional NoMachine Player sessions via “Grab the mouse input”, but it’s currently not possible with Web Player sessions. We fully understand the utility of being able to lock the mouse in the browser, so we will investigate adding the option to web-based sessions as well.

rfemali3, it’s not clear if your topic is about slow response or no image. Which problem are you actually experiencing. I understand that as a headless Linux, NoMachine works well. We have just verified to make sure.

Kroy has been kind and looked in the Rpi documentation for you for some tips. But I think that your question is more appropriate for the RPi forums perhaps because your configuration is not the standard manufacturer’s one.

Run sudo apt-get autoclean –sudo apt-get autoremowe. Run the following command to clear the package cache. Update: -sudo apt-update your system using the following command-sudo apt-get upgrade

Updating the server-side installation might help.

You’d have to try Enkidu. Could you also tell us whether logging in to the desktop first (on the local server side) and then starting your NoMachine session makes a difference? This would allow us to narrow down the investigation.

If you can still reproduce the behaviour, we will need logs from the Ubuntu server. Enable logs following the instructions here: https://kb.nomachine.com/DT11R00182, reproduce the problem, then gather the logs from the server. Send directly to forums[at]nomachine[dot]com.

Hi, when you log in, does the spinning wheel show in the NoMachine window. Do you get past this stage?

I never see the desktop

Do you see a black screen? Do you see a message of any kind?

Please submit a screenshot of what you see from log in to the final stage where the login doesn’t proceed.

We have reproduce something similar and there is a Trouble Report open: https://kb.nomachine.com/TR07S10316.

Hi, can I ask which folder your connection files are stored? By default they are in Documents/NoMachine on your computer, but if you have them on a network disk somewhere, for example, they may become unreachable for some reason.

Just for the record, the local network connections will only disappear if you choose not to see them, or if those computers are configured to not broadcast themselves on the local network See here for details on both of those: https://forums.nomachine.com/topic/how-to-clean-recent-connections-list#post-29887

From version 8 onwards.

[Britgirl]

Please everyone update their installations to the latest version. If you continue to have problems, open a new topic. Thanks!

[Britgirl]

This topic is now closed. Please contact us via the website (https://www.nomachine.com/contact-request) if you have feedback about the test package, would like to submit logs or provide other info that is useful for the investigation. Thanks!

Hi,

NoMachine for Linux includes a nxagent virtual X server that you can run, just to make one X server that the system can “see”, one that can run your desktop software and one you can connect to. When the Linux machine is headless, NoMachine detects that there is no X server running and prints the message:

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

to which you should click “Yes”. Did this appear the first time you connected? What happened? What happened the second time?

When you connected previously, and it was working, is it possible that a monitor was attached and on?  After connecting the first time, and then disconnecting the session, did the monitor turn off or maybe it’s a laptop and you closed the lid? It could be that the graphics card installed there did not correctly detect one or the other events (so it’s not NoMachine at fault here).

Take a look at this article and follow the tips there:

Also, if Wayland is the display server running there, please check the article here:

HI, with the release of v7 all details from the folder were moved to redis database to increase performance of the NoMachine server. I can confirm that to be able to identify session name with display and username included you can use the command --history --verbose.
