KDE Plasma cannot login after update

I get sent back to SDDM after I enter my credentials, regardless of whether I choose wayland or x11.
I understand there's been some problems with dependencies earlier today, but the update went through fine.
One thing that stands out is this: [WARNING] qt6-base was updated, qt6 applications will break until qt6gtk2 is rebuilt.
Do I just need to wait for that package to get an update too?

Edit: I tried again and X11 put me on the splash screen but it got stuck 1/3 of the way, I even got a "KDE Updated to 6.3" popup the first time and I could close it with the mouse, on subsequent attempts it just got stuck in the same spot.

Having the exact same issue, although for me, wayland will kick me back to SDDM, but X11 will just start an indefinite loading screen. My problems are exactly as are described in the final post of this thread: https://forum.artixlinux.org/index.php/topic,7337.0.html although despite being marked as solved a solution for that specfic issue was never posted there. It does look like the last qt6gtk 2 update was 2 days ago so perhaps it isn't updated yet.

I had the same issue after upgrading the KDE Plasma packages to version 6.3.1. I have found some packages yet with the older version 6.2.5 or even 6.2.4 - for instance by
Code: [Select]
pacman -Q | grep -E '6\.2\.(4|5)'
In my case world/kwin, word/layer-shell-qt, world/plasma-integration had an version older than 6.3.1. After upgrading them from world-gremlins, Plasma starts again.

I don't have gremlins enabled, and as far as I know disabling a repo after syncing with it can be a pain, I'd sooner consider installing the packages manually unless I'm completely misunderstanding something about how repos work.

I have both system-gremlins and world-gremlins permanently enabled. Until it did not cause any harm: If you put the respective <repo>-gremlins section after the <repo>-section in /etc/pacman.conf, no package <pkg> from <repo>-gremlins will automatically installed if <repo> has package <pkg>, too. The relevant part of my /etc/pacman.conf looks like:
Code: [Select]
[system]
Include = /etc/pacman.d/mirrorlist

[system-gremlins]
Include = /etc/pacman.d/mirrorlist

[world]
Include = /etc/pacman.d/mirrorlist

[world-gremlins]
Include = /etc/pacman.d/mirrorlist
If you want <pkg> from <repo>-gremlins, you can install it by
Code: [Select]
pacman -S <repo>-gremlins/<pkg>

Made an account to contribute and confirm I have the same problem.  Plasma is completely unusable.

Sadly the only solution was to switch to a different DE.  I've confirmed XFCE and Cinnamon are fine, and I think I'll make the latter my daily driver.  It's very similar to Plasma anyway.

Looks like they updated the troubleshooting page with this, but the first suggestion is logging into Plasma, which you can't do lol.  Didn't try using the terminal to edit /etc/environment though, maybe this will help someone else

@Dead_Baron You can login to the default Wayland session with a different display manager (I used LightDM) so maybe SDDM is the problem or some other package related to it.

On a currently updated system, the Plasma problem does not reproduce.

If the problem persists for anybody then pls provide details about the packages versions, xorg logfile, etc

It still happened to me but I put the env variable in /etc/environment and SDDM works fine now.

Same here.
Plasma/Wayland: Can't login as well.
QT_STYLE_OVERRIDE=Breeze didn't help.
And I can't login to Plasma/X11

semi noob here. not sure what you need but here's my best. timeshifting back to 2/19 after this post.

everything was working fine for the last half a year or so. yesterday I did sudo pacman -Syu and upon reboot wayland would throw me back to SDDM and X11 would launch kwallet but otherwise get stuck on splash screen.

installed openbox from ctrl+alt+f1 and rebooted and logged in to KDE/Openbox successfully

I tried to update sudo pacman -S extra/plasma-integration extra/kwin extra/plasma5-integration extra/plasma-meta extra/kde-system-meta as they were a version behind but no luck still can't kde wayland or x11

tried   QT_STYLE_OVERRIDE=Breeze as well as manually changing qt style

here's my /var/log/Xorg.0.log https://pastebin.com/pfJXbHac

here are my packages https://pastebin.com/dDKAuhL7

Using pacman -S is not supposed to be run; first pls run pacman -Syyu to ensure a full system update.

I did run Pacman -Syu, this is how I ended up with broken everything. I explain this in my third sentence that I ran pacman -Syu.

After running Pacman -Syu, I ran pacman -S to upgrade specific packages from the extra repo, following the logic of poster #3, wherein the packages I -S'ed had an older version in the world repo than their compatriots, in hopes that it would resolve the damage caused by pacman -Syu.

Prior to doing -S of specified packages (after everything was already broken from -Syu), I also attempted sudo pacman -Syu --overwrite \* $(pacman -Qnq) , and that also offered no remedy.

The problem was caused by the repo's not being consisent for a short time when you ran pacman -Syu. This resulted in a partial update. Running pacman -Syu again should complete the update now.

no. I just did pacman -Syyu and its broken again in same way.

pacman.log = https://pastebin.com/kU3FEt8m

to proceed I removed thunderbird because it needs old icu and manually installed nodejs-lts-jod as it was in conflict with -iron

then I did pacman -Syyu

at least openbox works... timeshifting back
