Error 108 for Windows -> Ubuntu with version 9.3.7

[danergo]

Folks, please help me.

I’m running the latest NoMachine on both my Linux Ubuntu (server), and on Windows 11 (client).

It was working before but now nxnode.bin segfaults.

Server: Ubuntu 24.04.3 LTS, Kernel: 6.8.0-90-generic

Journal log:

Problem is most probably in libnxdimi, because once I move it away, problem goes away (but then I can’t see the desktop, because it can not be detected):

sudo mv /usr/NX/lib/libnxdimi.so /usr/NX/lib/libnxdimi.so.disabled

I also did a gdb core backtrace for you:

Can you please help me solving this?

Hello, this looks similar to a Trouble Report already open, please take a look at the link here: https://kb.nomachine.com/TR01X11699. We can send you a test version with a possible fix implemented. Would you be willing to try it?

[danergo]

Hello @Britgirl, sorry for duplication, I didn’t find my earlier issue, hence I posted it again with more information and gdb logs.

Please go ahead and delete the other one for me if you can.

I took a quick look on your link, and it seems very similar if not the same issue as mine.

For the test version, yes please send it over, I’m willing to test it and get back with my results 🙂

[Britgirl]

Check your inbox, I’ve just sent you an email with the link.

I am having the same issue with MX Linux.

[danergo]

Dear Britgirl, the latest binary you’ve shared me fixed this issue.

Thank you very much!

One thing I don’t understand: my server has 2 displays (2* FHD 1920*1080), however the client sees them as one (3840*1080). Is there anything I can do with it?

[Britgirl]

Hi, we are aware of an issue with multi-monitors not being detected in some cases and it will be fixed in the next update.
