[SOLVED] Unable to start plasmashell

After a recent system upgrade and reboot, plasmashell fails to start.

Attatched is most of the output of "kstart5 plasmashell"

Could it be a cache related issues? Let me know if you need more info (I'd post more photos, but they are too large, and I don't have time to recompress them atm)

The "Cyclic dependency detected" error indicates an inconsitency.
Did you already try to reinstall plasma? Or uninstall an dinstall again
And also try with another user, as it might be config related.

Try start plasma with sddm, your can try delete cache of KDE too.

Yes, I already tried reinstalling as the normal user.
I'll add trying with another user to a list of things to try.

I don't think it's a dm issue, since "kstart5 plasmashell" doesn't work after logging in either.
I'll make a live usb and clear the cache.

If you can log into text mode you could try the following commands as user to clear kde cache and rebuild. They have solved issues for me in the past.

Code: [Select]
$ rm -rf ~/.cache/*
$ rm ~/.config/Trolltech.conf
$ kbuildsycoca5 --noincremental

Best regards

I tried all the suggested solutions to no avail, rebooting and all.

However, I figured out what the real source of the issue was from here: https://bbs.archlinux.org/viewtopic.php?id=258149

Oddly, it's an nvidia problem. Nvidia 450 and above causes plasmashell to crash.
Downgrading to nvidia 440 entirely solved my issue once I rebooted.

Unfortunately, that's not really odd at all. Just another entry in the long list of problems caused by nvidia. Glad you figured out the source of the issue though.  ;)
