(system log removed by admin, see attached)
Hi,
I’ve experimented with Wayland, upgraded to Fedora 42, but the problem persists. First, I have Wayland installed, but plasma-workspace-wayland package is no longer present in the distribution, which confused me. Second, I haven’t found any useful information in system or app logs, only this one on the client side – it may be red herring, but let’s take a look at it. I really need to have NX connection running…
Thanks
P.U.

OK, I’ve tried to restart with Wayland session. This time, server logs look different.
