Cannot open kde system settings, segmentation fault

After a recent topgrade, KDE's system settings fails to open at all. I change my wallpaper by right clicking on the desktop, but it's just a paired down system settings instance that only lets me change my wallpaper. Can also open a few other standalone settings like kcm_touchpad with commands like kcmshell6 kcm_touchpad, but again, those are limited to only those specific setting pages.

I remember I faced issues with apps like this because of some customization I did, global themes and GDDM and such, it showed me something like "could not find X installed" It's bazzite tho so you shouldn't worry i think, there are ways to go back before the upgrade In grub you have the os.tree 1 entry which is the previous one Also I think you can manually take a previous commit (I'm a noobie at rpm-ostree but I do know git)

This is still happening to me. According to journald, I get a big stacktrace, and the following two messages about the crash:

So, I can open it with sudo systemsettings just fine:

that is, it opens just fine. Not sure what those errors are about i can also open it in a container just fine (tried bazzite-arch, worked fine) https://paste.centos.org/view/fcacf899 here's a ujust device-info

It looks like upgrade has gone wrong and somehow just either missed files or just broke something What about doing this? https://bbs.archlinux.org/viewtopic.php?id=293984 Just looked online and this seems similar to your issue
Ashlynn
AshlynnOP3mo ago
ill try purging some files there later and see what happens I tried selectively deleting all kinds of folders and files in ~/.config and it's still not opening. Gonna try completely emptying .config next and see what happens I did make a backup, so I can easily restore it if need be Nope, still won't open
asen23
asen233mo ago
try .local/share too some kde setting are in there
Ashlynn
AshlynnOP3mo ago
alright
Emperor Lelouch Vi Brittania
Try a new profile if it still doesn't open then something went really wrong with the update otherwise it should be something in your home directory related to plasma config stuff you could reset that

Maybe try upgrading kde on a virtual machine, same exact upgrade with the same settings/theming as you had before and see if that fails Ive had worse issues than yours on nvidia with kde and I switched to gnome, wouldn't say it was flawless but significantly less issues, so you can try gnome perhaps to see how it is on a virtual machine And if you install kde for a second time I would suggest, if you theme it, to use themes that are relaltively popular with a high downloads I know that themes can run system wide scripts on your machine so it might change other things (SDDM theming broke the login screen on my machine for example)
Ashlynn
AshlynnOP3mo ago
I only use breeze lol I have no custom themes or anything Just.. stock kde any suggestions of what I should try deleting?
asen23
asen233mo ago
probably start with systemsettingsrc file renaming it should work append .bak or something
Ashlynn
AshlynnOP3mo ago
there isnt one
asen23
asen233mo ago
in folder systemsettings
Ashlynn
AshlynnOP3mo ago

Ashlynn

not sure then try something with plasma or kde in it
Ashlynn
AshlynnOP3mo ago
thats the backup i made before i started deleting stuff.. I tried deleting everything kde and plasma related and systemsettings still won't open
asen23
asen233mo ago
hmm, no idea then
Ashlynn
AshlynnOP3mo ago
well, i didn't delete keyrings, because i think i probably need that, and it's pretty unlikely that's the cause lmao There.. nuked all kinds of things in .local/share, nuked the entire .config folder.. let's see Oh and I did that in TTY that I opened before even logging into the user, so maybe that'll do something Lol nope, system settings still won't open I'm so confused Umm.. is there a way I can try to reinstall kde plasma or something?

Have you tried clearing your .cache folder? I've found that can solve all sorts of weird errors
Ashlynn
AshlynnOP3mo ago
Maybe ststemsettings got broken? Though idk why I'd still be able to open it with sudo but not as a user Hmm.. I'll give that a try LMAO sure enough, just renaming .cache to .cache.bak (and the same with the Cache folder) and now it works like nothing ever happened
asen23
asen233mo ago
cache is the first place to clear lmao
