Thanks for still looking for solutions.
I am not sure how to handle this. The drivers are in fact provided by the Laptop maker HP and the laptop and its driver updates are managed by my company’s IT, although I could update it manually, but according to HP I have the latest version. I did not find a driver on Wacom’s site that matches it, because it is HP hardware. I also do not fully understand the technical dependencies. So I am not sure what to tell them. Shall I contact Wacom or HP and refer them to you or some contact at NoMachine?
Also here, stopping the Wacom ISD service makes the NoMachine sessions stable. They were up an running for several days in a row without any issues.
This is acceptable, because I often use the laptop stationary at my desk at home without using the touchscreen. This the scenario when I mostly use NoMachine. I have a standalone Wacom tablet on my desk, and that seems to work also without the Wacom ISD service active.
When being on the move I use NoMachine less constantly, but sometimes I would like to have the touchscreen with pen. Now it looks like I would need to switch the Wacom service on or off manually as needed. This seems to work, but of course I would still prefer a solution in which there are not interferences.
Hi,
I have an HP Elitebook x360 1040 G8. And yes, Wacom ISD service is running. These laptops have a touchscreen with pen based on Wacom. I also have a separate Wacon tablet I use sometimes.
best regards, Jörg
Small Update: After it happened again today I also observed the process nxrunner.com being left after the nxplayer froze and was removed. I removed the nxrunner process, as well, but all other symptoms stayed the same.
Hi,
Here are some answers:
– I only use one player. In fact it is only one and the same Windows 10 Machine connected to my Ubuntu based server.
– I usually do not keep the main player window open, but in the past I tried this out and the main player window is also freezing.
– After the freeze is happening, the player window does not update any more and the mouse icon changes to the “wait, I am doing something” animation, but it never recovers from that and no updates are done to the player window. I usually press the windows close button of the player window. This brings up a message if I want to close it and after that the process is also gone if I remember correctly. This looks like the usual way Windows is handling unresponsive processes with open windows.
If after this I try to restart the player, I can see player processes being created in the task manager, but no player window appears. Also no player main window. If I do this several times, there will be more player processes started, but still no window. Only after a complete reboot of the Windows machine that runs the player I can get it working again.
– The process I see is nxplayer.bin. Of course there are many other processes running, but I did not find another one that I can directly associate with NoMachine or which looks suspiciously involved in the problem. Do you have some examples of processes I should look for?
I am suspecting some corporate security policies might be interfering here, because the player machine is my work laptop. I am using NoMachine to access a private desktop hosted at my home server and display it on the work laptop. I want to reach a clean separation of private task from work tasks. But I did not really find any concrete indication of my suspicion.
The main reason why I suspect it has something to do with inter-machine copy-paste is that it is working stable unless I used copy-paste a few times. If I want to recreate the issue, I would start doing copy-paste of text from the server to the client repeatedly. And it has to be copy-paste between machines. If I copy-paste within the server desktop accessed through the player window, it is stable, but if I copy in the server desktop and paste in the client native desktop, it works as well, but after doing this a few times the freeze happens. It is still kind of random and sometimes takes a little longer than other times, but this is the closest correlation of user actions to triggering the issue that I could observe.
– In the log folder I have a nxdevice.log and an nxinstall.log but not nxtrace.log. Can I activate a trace log somewhere?
Can it be that it has something to do with copy-paste from server machine to client ? I was using copy-paste of text quite a lot today and the problem appeared again and repeatedly. Before I was not using copy-paste and it was all quite stable.
I am on version 8.8.1 now on server and client and the problem is back. I did not experience it for several weeks and now it happened two times in one hour. Maybe I was just lucky all the time, because it used to happen quite randomly anyway.
I installed the latest version and was using it for a while. I must say I did not encounter the described problem for a while. I think since 8.6.1. it got better. There was also a major Windows update and several driver updates in the meantime. So am not sure what exactly introduced the solution. However the bottom line seems to be that the problem is gone.
Thanks for your help.
Hi,
I am still on 8.6.1 and used it for a while. I did not encounter the problem with that version. However there were also some windows updates in the meantime and I am not sure what exactly improved the situation. However, it appears that the situation has already improved or even got solved solved.
I am currently travelling, but I will try out the new versions next week when I am back. But already 8.6.1 seems to be good now. I cannot really be completely sure, because it was anyway a random problem that can only be reproduced by keeping sessions open for a long time. But I did not experience it since the last update and few windows updates.
I also replied to the mail I received about your question, but I can also repeat it here in case my mail answer did not reach anybody:
I tried it out and left both windows open. They both freeze/crash simultaneously. And no window of the client opens again after the crash. In Windows task manager I see processes of the client being started, but no window is opening on the client desktop. The server installation on the ubuntu system is however very stable and did never crash. In the meantime I upgraded Ubuntu to 23.04. All good on the server. Only issues on the Windows client.
In the meantime I also upgraded to the latest version 8.5.3 of NoMachine client and server. It looked good and stable for a while, but also the latest version did finally show the same symptoms. I guess I was just lucky for a while.
I would not even mind that it occasionally crashes. Just restarting the client would be ok. But it is annoying that it crashes in a way that only a complete reboot of the client machine is helping to recover.
Hi Britgirl,
Thanks for your help. I started now with the software update only. I will observe how it performs and if the issue is gone with the new version. By the way, I updated the version on both, the client and server, to 8.3.1.
If this does not help, I will try your other proposals. I think hardware decode/encode is a useful feature and I only want to disable it if the new software version still shows the same problem.
By the way, the load on the GPU caused by hardware decode is quite low in my opinion. Windows task manager shows around 20-30% 3D load and 5-6% video decoding load for the Iris Xe GPU on my laptop with the NX client. I had to play a video on the shared desktop to cause a continued image change and see any sustained GPU load at all. But this is of course expected.
I think I have to observe this for some time before I declare the problem gone or not as the described problem happens only once in a while now. It is rare enough to accept it if the only thing needed would be to restart the client software. But having to reboot the entire client machine is the annoying part.
I have some testing to do now and I will report on the results.
Hi,
Thanks for your help.
I did include the logs from the .nx folder that did show successful sessions as well as those that show up after I had to kill the client and restarting the enterprise client did not produce a window. The latter ones are the very short session logs.
Please note that I recently use the server connection over an ssh tunnel with implicit forward of port 4000. The connection is therefore made to localhost:4000. If I do not use the tunnel, but direct connection, the symptoms of occasional freeze with killing the client process and then needing a reboot before a client window is available again are the same. I use the tunnel, because I also wanted to use the connection from remote, but do not want to open the server port through router port forwarding and expose it publicly. All logs attached in the mail are from sessions in my home LAN.
My use case is connecting to my home server from my work laptop.
In my setup the server is my private home server and the client is my work laptop. I suspected that the problem is related our enterprise security policies, which are allergic to incoming connection to our devices. Therefore the server component of the free Windows software is a problem. I do not need the server on the Windows system. I uninstalled NoMachine free version and downloaded and installed the Enterprise Client. From what I can see it is basically the same client, but without the integrated server. This seem to work. I did now use it for a few hours without any freezing or other strange behavior. It is actually very responsive even in higher screen resolutions.
