[Solved] KDE issues after update

Today I updated to the most recent KDE version, but some problems start occurring.

- Most applications are missing the top "control strip" that contains minimize/maximize close and the bar you can click and drag to move the window. Firefox has been an exception, it has that strip but it cannot be dragged around
- Opened applications do not appear in the bottom bar. Combining this and the previous issue, I cannot close most applications
-  Windows do not come into foreground when I click on them

I am not very faimiliar with how KDE works so I would appreciate any help debugging this

Re: [Solved] KDE issues after update

There's no window manager running (crashed? Or did you change the KDE WM to some bogus command?)
Check https://wiki.archlinux.org/title/Core_d … _core_dump and your system journal for the boot:

sudo journalctl -b

Edit: traditionally, those "strips" are called the "window decoration"

I never made any modifications to KDE (willingly at least). I am not even sure what my WM is

The only thing I did outside of just regular PC usage was solving the linux-firmware conflict after the most recent update with the suggested guilines my removing and reinstalling linux-firmaware https://lists.archlinux.org/archives/li … 2UXXD7SMC/

journalctl -b output: https://pastebin.com/BFCKd6Li

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

PSA: check the last link below and also make sure that your xinitrc imports the environment from logind (2nd blue note)
