Hi,
this is really strange even on a headless server. Please gather server side logs as explained in https://www.nomachine.com/AR10K00697. You can send them to forum[at]nomachine[dot]com.
Hi,
the display service on the server can’t start up because it cannot find any free TCP port in the given range. This range can be modified to avoid conflicts with other applications as explained at point 6 of the following article:
https://www.nomachine.com/AR11L00823
However the fact that all those ports are unavailable is abnormal and it should be checked if there is an application that is misbehaving. You can see yourself what are the busy ports in the nxserver.log file:
2020-09-28 11:40:57 903.811 29296 NXNODE TCP port '7002' is used by another application. 2020-09-28 11:40:57 905.853 29296 NXNODE TCP port '7003' is used by another application. [...] 2020-09-28 11:40:58 376.810 29296 NXNODE TCP port '12200' is used by another application.To check what application is keeping those ports busy you may try one of these methods:
Just to be sure that it is not related to a Cinnamon issue, can you tell us if restarting the NoMachine server only (without rebooting the machine) is enough to fix the problem? Also logs could be useful to understand better what is happening (https://www.nomachine.com/DT10O00163#1). You can send them to forum[at]nomachine[dot]com.
Hello,
should the problem happen again, please gather server side logs as explained in https://www.nomachine.com/AR10K00697. You can send them to forum[at]nomachine[dot]com.
Hi,
please collect the logs from the server (https://www.nomachine.com/AR10K00697) and the client (https://www.nomachine.com/DT10O00163#2). You can send them to forum[at]nomachine[dot]com.
Hi Karl-Peter,
do you have a high resolution monitor attached to the Pi (e.g. 4k) and you run the NoMachine player fullscreen or maximized? Does performance depend on the NoMachine window size (i.e. does it get significantly better if you reduce the player window to a smaller size)?
Hi,
in order to exclude any networking issue, can you try to lower Display quality to the minimum level (slide bar on the leftmost position) and uncheck ‘Disable multi-pass display encoding’? Then I would also try to disable UDP.
Is the server headless? If so, is there any chance you can attach a monitor there and see if anything changes?
Hi,
what you say about not using the GPU and even more what you see in the Start menu makes me think the Windows box you connect to is headless. Is it the case? If yes, can you try to attach a monitor and see if these symptoms disappear?
Sorry for the delay, I thought i had already replied to this with some comments on the logs. Anyway, in the logs I see that hardware decoding is effectively used. Is the server headless? If yes, can you try to attach a monitor?
Hello,
do you have the possibility to connect to the same PC from a different client in the same LAN? In this way we could rule out any problem with the Windows machine you connect to and with network.
Hi,
thanks for the feedback and for the last head up. We think we know the reason and we will be addressing that too.
Thanks for the update.
The issue with the “ghost mouse” is known, it can happen under some circumstances and it will be fixed probably in the next update. The performance problem is not, so I wonder if this can also be related to the drivers. You may try to disable the ‘Use acceleration for display processing’ option in the Server preferences, Performance tab on the machine where you connect to.
If in the meanwhile you would like to send the logs, I’d be glad to take a look.
Let me clarify: the position where application windows are disaplayed doesn’t depend on the NoMachine software, but it is possible that, if NoMachine resizes the remote physical desktop to a lower resolution than the one you use when being physically in front of it, some of the applications remember the previous position and are moved off screen after the resize (this anyway looks like a bug in the window manager that should prevent that). Assuming this is the case, you can try to choose a larger resolution for the remote dekstop (you can find a Resolution slider in the session menu panel), if available.
Does the paid version use a different way of connecting?
NoMachine products from the Terminal Server family (from Workstation on) allows to create multiple virtual desktops, that are independent from the physical desktop of the server and have no constrain about possible resolutions (any screen size is possible). This also means that multiple users can use their own remote desktop independently.
Hi,
there is one known issue in version 6.11.2 that can cause a white screen:

But to confirm whether it is the same issue or a different unknown one, we would need to see the logs.
