Dolphin thumbnails not loading anymore

Issues & Assistance KDE
1

I’ve had my garuda Dragonized installation since February 2025.
But since May, I’ve noticed that my thumbnails in Dolphin don’t show anymore.

I’ve done following steps:

  1. deleted ~/.cache/thumbnails

  2. Checked the dolphin settings. They say "preview for every file of any size

  3. Checked multiple system packages, including kio

Then I noticed, when I open dolphin as root (right click, admin actions, open in dolphin), a new window of dolphin opens. The themes are missing, it’s white and default, but the icons are back.
So somehow my user config is corrupt? But I checked the setting in dolphin with my user and those seem correct. What am I missing?

Would be really helpful if someone knows what to do.

Thank you and best regards
Ven

Here is the ~/.config/dolphinrc file:

Welcome aboard. Have you done a reboot. On Wednesday I had the icons disappear and while I was trying to figure it out a few things started acting up finally making me have to power off the system. All has been fine since. I suggest a reboot to see what you get. Please also add your garuda-inxi to your first post.

Thank you. I’ve had this problem for many weeks now, so I did many reboots. And I’ve added my inxi.

Best regards

Try creating a new user, log in as them, and see if the thumbnails show up in Dolphin. If they do, check for differences in the dotfiles of the two users. Are ~/.config/dolphinrc and ~/.config/kdeglobals the same (between the two users), for example?

I’ve created a new user over the kde settings (useradd won’t apply any themes).

Dolphin thumbnails are working there. Then I’ve compared and even replaced ~/.config/kdeglobals and ~/.config/dolphinrc.

I’ve cleared the file index database and restarted indexing again-

Something’s wrong with my user then, but I dpn’t know what

6

I don’t know either…but KDE has always had a habit of having config files kinda scattered everywhere :wink:

7

well mine started working again, I’m guessing a package update fixed it.

8

If, you should use Garuda Settings Manager.

and

pls bios update

Thank you for the suggestion, I updated my bios just two weeks ago, it’s now at version 3003 with date 05/05/2025.

But that didn’t fix it.

The previews started working for a day, and then stopped working again.

And as it only affects my user, I think it’s a user-specific problem, not a system-problem
