Created attachment 150403 [details] Global Env Files and journald Log SUMMARY Describing this issue is a bit strange, since it's just severe enough to be a pain but not severe enough that it isn't usable? I have "control" of my desktop but only thanks to Yakuake auto-starting, but what happens here is this: the (icons-only) task manager and the "desktop" (where you'd see wallpapers and application icons) are completely missing. (It doesn't even load my wallpaper; there's nothing to interact with at all if you don't have a terminal that auto-launches on login.) The only semblance of whatever is going on here is some vague failures in journald that I don't understand at all. This only started the other day.... I want to say roughly around June 30th(? Can't quite remember) after an update. I've no clue what's going on nor how to fix it - rebooting doesn't help and my filesystem checked out as clean/non-corrupt. :/ STEPS TO REPRODUCE 1. Login to Plasma via SDDM OBSERVED RESULT The Plasma shell doesn't load correctly EXPECTED RESULT The Plasma shell should load as normal SOFTWARE/OS VERSIONS Linux : Arch Linux Kernel: Linux 5.17.9-258-tkg-pds-llvm ( https://github.com/frogging-family/linux-tkg ) KDE Plasma Version: 5.25.2 KDE Frameworks Version: 5.95.0 Qt Version: 5.15.5 GPU: Nvidia RTX 2080 Ti GPU Driver Version: 515.48.07 (Proprietary) ADDITIONAL INFORMATION Moving my entire user config folder to a temporary location does not seem to fix the issue, so something deeper is going on, somehow. :/ I'm including the mentioned journald log and files that set environment variables, though nothing I've done seems to make any difference in solving (or cause) the issue. :/ I did additionally (originally) use an x86-64-v3 repo for this, but I did downgrade from that repo to the official Arch repos and this made no difference - the issue persisted. :/ And to clarify, I only have one display connected.

This is a local/installation problem.
@Antonio This wasn't an issue literally overnight, so were components seperated from pre-existing packages to new ones?
Additionally, I searched for the library that claims to be missing and my package manager says I have it installed; please don't dismiss this issue so readily without conversation.
Additionally, everything is from that other repo (originally); regardless, I did downgrade *everything without exception* to the *official repos* and the issue *still persists.* (pacman -Syuu) I guarantee you, at that point, there is nothing being mixed.
I'm afraid Antonio is right, or at least in the ballpark. The error you're seeing is caused by mixing incompatible library versions that were not all compiled against one another, and there is no chance that it's a KDE problem. It's either a distro packaging problem, or a user configuration problem.
