Created attachment 173808 [details] Log of one of the affected bad boots. I do Ctrl+Alt+F3 to go to tty3 process while I'm stuck at the black screen if that's a useful marker in the log. SUMMARY After upgrading to KDE Beta 6.2, upon logging in I am brought to a black screen with a cursor and nothing else and I never make it to the desktop. This does not repro when using X11, even though I have been using Wayland successfully ever since the Plasma 6 beta. STEPS TO REPRODUCE 1. Turn on PC and login at SDDM 2. Hit black screen OBSERVED RESULT Stuck at black screen with a cursor. The screen has a noticeable performance hit every few seconds, which gives the impression something is continuously trying to start and fail. EXPECTED RESULT Make it to desktop SOFTWARE/OS VERSIONS Operating System: EndeavourOS KDE Plasma Version: 6.1.90 KDE Frameworks Version: 6.6.0 Qt Version: 6.8.0 Kernel Version: 6.11.0-arch1-1 (64-bit) Graphics Platform: X11 Processors: 24 × AMD Ryzen 9 5900X 12-Core Processor Memory: 62.7 GiB of RAM Graphics Processor: NVIDIA GeForce RTX 3080 Ti/PCIe/SSE2 ADDITIONAL INFORMATION As noted above, the perf hit makes it feel like there's some process rebooting continuously while I'm at the black screen. The kauth crash in the log also shows up in the x11 session, so not sure if related. I tried re-installing plasma, kde, qt6 packages, and also removed Endeavour SDDM and Endeavour Plasma themes.

In this state, can you hit Alt+Space to get KRunner and open Konsole? If that works, can you try launching plasma with `plasmashell`?

So nothing actually rendered and I could still only see a black screen and the cursor. I still tried to type in the commands. However I noticed, the cursor was changing its icon as if there was the window there (so from a standard pointer to the typing indicator, and window resize arrows). So it seemed like I did launch it potentially since the cursor was recognizing a window being there at least. But nothing still showed up. Attaching logs from this run.
Created attachment 173840 [details] While at black screen, did Alt+Space, then typed konsole, and then plasmashell to attempt to launch shell. Nothing rendered however and I remained at black screen.
seems that plasma indeed fails to start Sep 17 17:36:04 brian-endeavour plasmashell[1589]: kde.plasmashell: Aborting shell load: The activity manager daemon (kactivitymanagerd) is not running. Sep 17 17:36:04 brian-endeavour plasmashell[1589]: kde.plasmashell: If this Plasma has been installed into a custom prefix, verify that its D-Bus services dir is known to the system for the daemon to be activatable.
seems kactivities/kactivitymanagerd is not installed seems a local setup or distro issue
