[SOLVED] Unable to start plasmashell 21 September 2020, 01:00:49 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) Last Edit: 25 September 2020, 16:13:43 by nous
Re: Unable to start plasmashell Reply #1 – 21 September 2020, 20:33:29 The "Cyclic dependency detected" error indicates an inconsitency.Did you already try to reinstall plasma? Or uninstall an dinstall againAnd also try with another user, as it might be config related.

Re: Unable to start plasmashell Reply #4 – 23 September 2020, 14:37:11 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 --noincrementalBest regards
Re: Unable to start plasmashell Reply #5 – 24 September 2020, 00:47:35 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=258149Oddly, it's an nvidia problem. Nvidia 450 and above causes plasmashell to crash.Downgrading to nvidia 440 entirely solved my issue once I rebooted.

Just another entry in the long list of problems caused by nvidia. Glad you figured out the source of the issue though. 2 Likes
