Fedora 42 KDE / Wayland / 9.0.188 white screen

[sbalmos]

I can’t tell if this is a regression of the previous TR05V11141 that related to KDE 6 / Wayland white screens and EGL or a new error. But in a fresh install of Fedora 42 KDE Edition as the server, with 9.0.188-11 server and 9.0.188-11 Windows client, attempting to connect gives the dreaded white screen and an eventual Connection reset by peer (error 108). Attached are the client and server logs as well as the systemd service journal logs for nxserver. It looks as if nxnode / nxserver is unable to load the proper Wayland plugin.

Hi, can you gather the logs with debug enabled? Please follow the instructions in this document: https://kb.nomachine.com/DT07S00243. It’s valid for v9 as well. Reboot the server, or logout and log back in. Gather logs again. Thanks!

Debug level server-side logs attached.

Hi,

thanks for the logs. Can you please run these 3 commands in a terminal on the server and show us the output?

1 echo $LD_PRELOAD

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

3 sudo getcap /usr/bin/kwin_wayland
