Could something have changed in your LAN’s configuration?
Is the phone’s IP address in the same subnet as the server?
Can you ping the phone from PC on which NoMachine server is installed?
Can you ping desktop client from PC on which NoMachine server is installed?
Can you ping the PC (where you have installed NoMachine server) from the desktop client?Are you sure you’ve (or someone else) has not changed the port on the server to a different port than 4000?
To what port on the router did you redirect the connection from the Internet to the NoMachine server?What is the OS on the NoMachine server? Does the server have a firewall?
Can you temporarily turn off firewall during LAN connection tests?Hi, we need to check something first. Can you disable Sharpkeys (for this quick test) and then check again if shortcuts are working as expected or are still wrong within the NoMachine session.
Hi,
can you tell us the complete DefaultDesktopCommand you are using?
We see that you are probably using custom built binaries. Have you checked that you can login to the GUI locally? I.e not with NoMachine involved.
If you can, open a terminal and run
env > /tmp/env-i3.txt. Send us the file and we’ll take a look.Hi Mark,
Those exit codes, actually, are the exit codes of the external programs run by the server, with these external programs being mainly “system commands” of the specific platform, the specific OS where the server is running on. So, to understand what the exit code means, you would need to know, for each exit code, what was the external program that was executed. These exit codes, for the record, are very “application specific”, and so, if I were you, I wouldn’t give much importance to these. Of course the server DOES GIVE them the importance they deserve, since the server KNOWS what the program is that is run and also what exit code the program will return, for every error the server expects. So, all in all, difficult to give you an informative answer. Need to know the context, what the server is doing, what is the program that is run and the exact log lines the server prints, for the procedure, before and after.
If you send us a few of the log excerpts of the problematic user sessions (submit to forum[at]nomachine[dot]com) and we can then give you some pointers to help you with your own debugging 🙂
Hi, I removed your screenshot because it contains sensitive information (I.e your IP address).
Please provide the following:
1) a video showing the flickering issue (you can send to forum[at]nomachine[dot]com. Make sure you use the topic’s title as the subject of your email.
2) NoMachine Player logs (see here for instructions https://kb.nomachine.com/DT07S00243, scroll down to Collect Client Side Logs)
3) NoMachine server product and version.
Do I have to recopy text to clipboard after connecting to Ubuntu.
Yes, you do. For security.
If we allowed to forward the clipboard content that was copied before the connection, other users connected to the desktop could be able to see or even paste it.
Hi, this usually means that the client side cannot reach the NoMachine service on the remote host. Are you able to connect with WiFi when you are on the same LAN as the NoMachine server? What version and products of NoMachine are you using on the client and server sides? What OS is on the phone, what is on the server side?
We are not aware of similar problems when connecting to Xubuntu 20.04. The logs you submitted show several errors suggesting a misconfigured localhost.

From an earlier comment of your “When I disabled it before, I only did it on the Windows machine. Should I have also disabled it on the Linux (server) machine?” – no it was not necessary 🙂
HW decoding is a client-side setting (the device you are connecting from), so in your case you only needed to disable it on your Windows computer.
Hi, disabling HW decoding on the client is done in the Player configuration, apologies if this was not made clear:
You need to edit the file $HOME/.nx/config/player.cfg and set the configuration key “Enable hardware accelerated decoding” to “disabled”.
The options are:
– true: hw decoding enabled
– false: hw decoding disabled (but libraries for hw decoding are loaded)
– disabled: hw decoding disabled (libraries for hw decoding are never loaded and the checkbox is greyed out inside menu panel)You can also toggle HW decoding from the connection menu (during the session), but this will toggle between true and false, see above).
Can you confirm that the player.cfg file has “disabled” next to the Enable hardware accelerated decoding key?
Each of those Linux system bash exit codes could relate to a number of different processes, such as nxexec run by nxserver, nxrunner run by nxnode, gnome run by node and so on. It would be better to see the logs of a session in which you have encountered a problem i.e a recent dropped or lost session and not one from 1 year ago to give you the reasons for specific exit codes during the loss of a session. Some examples are, exit code 11 generally means that the process crashed for segfault, exit code 9 that terminated by SIGKILL, exit code 15 that terminated by SIGTERM (more gracefully). The description within the logs should suffice and where it doesn’t, we can of course improve.
Hi, we are aware of an issue related to Wayland and the workaround for the moment is to disable Wayland and user X.org. Can you send us the logs of the remote Kubuntu server so we can check it’s the same issue we are currently investigating? Please consult the following document for instructions on how to extract the logs and submit them here, or send them directly to forum[at]nomachine[dot]com making sure to use the title of this topic as the subject of your email. Thanks!
