Kubuntu 25.04 KDE Wayland black screen (NM 9.0.188)

[theblackhole]

Hi,

The server is installed on a workstation and I shut it down almost every day (so multiple reboots since I updated NoMachine).
Unfortunately I can’t send you the logs because all my emails have been rejected (spam detection), even from several other email address and even without the attached zip, with only a password for a password-protected transfer/hosting service (where I would’ve posted the link to the file here) :/

Is there another secure way I can send you my logs (or a password to download the logs) ?

Also, since you mentioned a new libnxegl library, here’s the sha256sum of the one I have, in case you want to check if this is indeed the correct one: 8422d2b53709d7748fa024af8b0c715e60a0fb46bf7d6b453e9adf41cc9992b6  /usr/NX/lib/libnxegl.so

I will contact you from forum[at]… as a test. Please reply to my email when you have received it.

Logs have been received and are being analyzed.

@theblackhole,

it looks like you still have the WaylandModes key in /usr/NX/etc/node.cfg set to ‘drm,egl,compositor’. Please try to restore it to its default value (WaylandModes egl,drm,compositor) or comment it out altogether. In version 9.1.24 all known issues with the egl mode were fixed.

If that doesn’t solve the problem, please collect a new set of logs after having restored the key to the default value. Also tell us whether the server machine is headless or its monitor is turned off. In that case, does anything change if you connect a monitor or turn it on?

Looks like i still have the same issue, however it seems that the NoMachine Target (Server) crashes, Kubuntu 24.04 LTS with all updates.

Anybody else still suffering this?

Regards

Michael

Can you clarify what is crashing exactly? A system process or the NoMachine server? Is there a crash report to share with us?

Please also gather the logs as explained in https://kb.nomachine.com/DT08U00298#1. Also the journalctl output can be useful. You can send all of that to forum[at]nomachine[dot]com.

I still have the same issue using 9.2.18 on both client and server on Fedora 42 and Wayland, I can connect to an existing session and I can move the mouse and click and interact, but the screen on my client is completely black:

drukob@icecube:~$ ls -l /etc/xdg/plasma-workspace/env/ total 28 -rw-r–r–. 1 root root 508 Feb 15  2025 env.sh -rw-r–r–. 1 root root 299 Jan 17  2025 fedora-plasma-cache.sh -rw-r–r–. 1 root root 644 Feb 15  2025 gtk2_rc_files.sh -rw-r–r–. 1 root root 175 Feb 15  2025 gtk3_scrolling.sh -rw-r–r–. 1 root root  52 Jul  3 02:00 ksshaskpass.sh -rw-r–r–. 1 root root  42 Nov 10 23:57 nx-sourceenv.sh -rw-r–r–. 1 root root 109 Feb 20  2025 ssh-agent.sh   drukob@icecube:~$ sudo getcap /usr/bin/kwin_wayland –> no output drukob@icecube:~$ echo $XDG_SESSION_TYPE wayland

Attached the logs (had to seperate and split server.log due to size limitation), my config

Please reboot the system (or at least restart the desktop manager). This will make sure the updated libnxegl library is loaded into the system. If you still experience problems after that, please send the logs again. Thank you for your cooperation!
