Plasma 6 wayland connection issue – 104 error

[jjgalvez]

Afternoon,

when I try to connect between two computers both running Arch and Wayland with plasma 6 I get a white screen which then becomes a 104 connection reset by peer error. This looks like the same error in TR07U10921.  I’m attaching the logs hopefully they help. Unfortunately I can’t drop back to xorg as it causes issues on my machine coming out of sleep.

happy to provide any additional information / logs that might be useful

Hi, can you submit server side logs so that we can check if it is indeed that TR? You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243

Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!

[jjgalvez]

Thank you I will submit the logs later today

[jjgalvez]

server and client logs sent. Hope they are helpful

[Britgirl]

The logs show that the issue is actually a different one. This https://www.nomachine.com/TR03U10784. Support for 10 bits channels is planned, most likely in one of the minor releases of the v9 tree.

interesting, are there any workarounds or do i need to set the color depth on my desktop to something less than fullcolor?

[Britgirl]

Can you tell us what configuration you have in order to get 30 bit per pixel? We can verify it first in our labs.

Afternoon Britgirl, thanks for the quick reply,

I’m running Arch (EndeavourOS) with KDE Plasma 6 Wayland  (including SDDM on Wayland). I’m attaching a screen shot of the system info for reference.

Nomachine was installed by the AUR

We were more interested in your specific display settings. What’s the monitor model btw?

[jjgalvez]

Monitor MSI Optix Mag321CQR

resolution: 2560×1440 @ 60 Hz
scale: 120%

RGB Range full color

@jjgalvez,

please show the content of the ‘/usr/libexec/plasma-dbus-run-session-if-needed’ script. Note that this file could be in a different path, so you can use the ‘locate’ command to find it.

Also show the output of:

ls -l /etc/xdg/plasma-workspace/env

[jjgalvez]

apologies for not replying sooner. On my machine I don’t have a plasma-workspace/env folder other than ~/.config/plasma-workspace/env which is empty

[fra81]

Hi,

did you also check the content of the /usr/libexec/plasma-dbus-run-session-if-needed script?

Besides, you can try the following steps:

1. Create the /etc/xdg/plasma-workspace/env directory

2. Place a nx-surceenv.sh script in it containing only this line: export LD_PRELOAD=/usr/NX/lib/libnxegl.so

3. Reboot

4. Make sure the libnxegl library is preloaded (the output of the sudo netstat -anlp | grep egl command shouldn’t be empty)

 

Let us know the results 😉
