Description acidrums4 2018-08-07 21:24:41 UTC

(Reporting as a bug as I got no help on forums).

From 5.12 onwards, every time I right-click on the desktop or try to change lockscreen wallpaper, the"Wallpaper type" (or what is says in english) selection widget has no options.

I tried creating a whole new user on my system, but from there the thing is the same.

Expected results: Being able to select "static image", "color" and etc (and being able to select an image when selecting "static image") when changing lockscreen and desktop wallpapers.

Still I can change desktop wallpaper by dragging an image file from Dolphin. Alas I don't know if there's a similar workaround for changing the lock screen wallpaper.

The output of plasmashell can be found here (there are some weird things there, but I don't know if they're relevant to this): https://pastebin.com/w2rcTadT

OS: Gentoo amd64
Plasma 5.13 & Frameworks 5.48 from the KDE overlay.

Thank you so much for your quick answer. Here's the ls output:

ls -alLh /usr/share/plasma/wallpapers

> kpluginindex.json

try either deleting this


or running 

sudo kpackagetool5 --generate-index -g



And if you can read gentoo packaging to see if the emerge is calling something like that last line explicitly that would be much appreciated. It's not from any KDE code.

It did it! Thank you so much :)

Well, I just did:

grep -r kpackagetools5 /usr/portage
grep -r kpackagetools5 /var/lib/layman/kde
grep -r kpluginindex.json /usr/portage
grep -r kpluginindex.json /var/lib/layman/kde

and all of them returned nothing. Not sure if that's what you meant but I guess it didn't came from any KDE ebuild but rather from an plasma widget I got from the store quite time ago.

However, than you so much for your help. Leaving this as invalid, as I could finally confirm this wasn't related to upstream.
