Dolphin won't start and freez Cachy

Help
1

Hi forum people,

since yesterday Dolphin wont open. It started with hickups and system freezing. I tried with system update and restarts but now its just doing the jumping animation beside the cursor and nothing more.
I installed Thunar to do file stuff but i want my dolphin back! :slight_smile:
I run CachyOS with all updates installed..

Has anyone an idea how to deal with that?

thanks for your help!!

You can’t receive help (or try to reproduce) if you don’t say the version of Dolphin, KDE Plasma, KDE Frameworks, etc. Something as this (results of type kinfo):

KDE Frameworks Version: 6.29.0

I don’t have this problem on CachyOS. See kinfo below :

Operating System: CachyOS Linux

dolphin 26.08.0

Can you launch Dolphin in a terminal (Konsole)?

5

good so its nothing that bothers many…

If you ment with lauching Dolphin in terminal to open a folder, this is the output:

Bildschirmfoto_20260827_203457
Bildschirmfoto_20260827_2034571031×108 11.6 KB

funny that i can enter the filepicker from the browser… isnt that Dolphin too?
so something works i guess?

Thanks that you guys try to solve my problem with me!!

6

Which browser ?
And a browser is not a filemanager.
Could you run dolphin in konsole without folder ? Just type ‘dolphin’

You can try too krusader. It looks like Dolphin. And it has been developed for KDE

7

The Vivaldi filepicker looks alot like Dolphin thats why I thought it´s maybe a part of it but ok…

Dolphin in Terminal gives the same result:

❯ dolphin
kf.i18n: Trying to convert empty KLocalizedString to QString.
kf.config.core: "KConfigIni: In file /home/sim/.config/session/dolphin_dolphin_dolphin, line 5:" Invalid entry (missing ']')
fish: Job 1, 'dolphin' terminated by signal SIGSEGV (Adressbereichsfehler)

Krusader is actualy a nice replacement but i like Dolphin more. Until Dolphin is fixed ill use it. Thanks!!

Signal SIGSEGV is a kernel error right?

My solution is to switch back to Bazzite… Since I was on Cachy i had a worse Gaming experience, System freezings and weird problems like that with Dolphin. Maybe Arch based is not my thing^^
Thanks for looking at the problem but nearly every problem i had was “solved” by “just use something else and let the program unfixed” and I dont like that…

No, SIGSEGV is a segmentation fault in the application. And to diagnose it you need to post a backtrace.

10

You have a corrupted stored dolphin session file.

The fix:

rm ~/.config/session/dolphin_dolphin_dolphin
11

As i said, i switched back to Bazzite for several reasons. Thanks alot for your solution i canot say that this workes but its more than i could find in other forums. :slight_smile:

Maybe it helpes someone else​:heart:

I’m having the same issues with version 26.11 from KDE unstable.
Here is what I’m seeing in the logs.

9/14/26 8:12 PM systemd Started Dolphin - File Manager.
9/14/26 8:12 PM dolphin /usr/bin/X11/dolphin: symbol lookup error: /lib64/libdolphinprivate.so.6: undefined symbol: _ZN3KIO23RenameFileWarningDialog6resultEb

Had to switch back to 26.08 from distro and it works.

That’s a packaging issue, your installed kio is not recent enough.

Here is what I have. So it’s a distro issue?
