Hello, i recently switched to Linux and im using KDE Plasma.
I set my wallpaper to slideshow mode and set the change timer to 48h, however, every time i restart/log out, the wallpaper changes (it picks a new picture from the slideshow) even tho the 48h havent passed yet.
Is there a way i can change this without third party software, and if not- please suggest some lightweight wallpaper software.
It looks like that you have already in KDE several options. You might check that you just activate on and deactivate the others. So you can see on which option you are making changes.
On the article below it shows that there is the slideshow & plasma wallpaper plugin. As mentioned just focus on one option at once. So you can see which tool is working as you expect.
