journalctl error
Comment 4 Ban Alexandru 2022-11-17 13:48:47 UTC
I should also mention I saw that Powerdevil also failed to start, not sure if this is related.

Yesterday I updated my system with `sudo pacman -Syyu` and today it just freezes the screen .

If I try to launch plasmashell through tty2 it says this:
```
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

Aborted (core dumped)
```

I've attached more pictures.

I've tried reinstalling plasma-workspace, plasma-desktop, plasma-framework and qt5-base, but it still doesnt work (I have QT5 not 6, but I don't know how to edit my first comment)

I've also tried: https://forum.manjaro.org/t/how-to-fix-broken-kde-desktop-qt/70459

'env|grep DISPLAY' doesn't display anything

error from "kstart5 plasmashell"
Comment 11 Antonio Rojas 2022-11-17 16:16:22 UTC
All those errors you posted are happening because you are trying to run "plasmashell" from a tty, which is not possible. You need to run it on an already existing X instance. What you need to do is debug your errors on boot, which are unlikely to be related to KDE at all. I suggest you ask on the Arch forums (if you're actually using Arch and not some random derivative)

What Antonio said
Comment 13 Ban Alexandru 2022-11-17 23:07:50 UTC
Oh, alright. Thank you guys, I'll either ask there or just reinstall Arch
