[SOLVED] Plasma - missing deskop icons preview and folder thumbnails

Hey,

I have a very peculiar problem related to showing icons preview on a desktop as well as folder thumbnails.

1) Missing desktops icons preview

Image files on a desktop have no preview. The option under:  Context menu -> Icons -> Show Previews is checked (including preview plugins)

What's more interesting, if I browse desktop files through Dolphin all the previews are displayed correctly

2) Folders which contain graphic files have no these little thumbnails on a folder icon.

Again:  Configure Dolphin -> Interface -> Preview -> most of the types including folders are checked.

I'm quite sure these all worked in the past but it stopped at some point of time. Reinstalling plasma, cleaning plasma config, removing cache didn't solve anything.

I created a new user to rule out local settings issue but I faced exactly the same issue  which would indicate missing packages but I have plasma-meta package installed along with a few kde-applications including the ones mentioned in Arch wiki

pacman -Qs thumb
local/ffmpegthumbs 25.12.3-1 (kde-applications kde-multimedia)
    FFmpeg-based thumbnail creator for video files
local/kdegraphics-thumbnailers 25.12.3-1 (kde-applications kde-graphics)
    Thumbnailers for various graphics file formats

I'm using Arch with the latest plasma, AMD card, wayland session, etx4 fs, all directories are located under my home directory. I didnt' find anything interesting in the journal.

I will be grateful for any tips.

Sorry I have no solution for you.
I can only confirm the same problem with Dolphin on my system since several days (after an update). Only the preview panel is working fine when the mouse pointer is over a file.
I had hope that the problem would be quickly corrected, but so far no good.

Re: [SOLVED] Plasma - missing deskop icons preview and folder thumbnails

I have solved it, the issue was related to mounting options of /home directory. For long time I had these options generated by genfstab:  UUID=long-uuid-number      /home           ext4            noauto,x-systemd.automount,rw,relatime,data=ordered     0 2

After I changed to default all the thumbnails reappeared and solved my issue.
