I have finally located the screen lock location for Plasma under Mageia #6 in system Settings. But there doesn't seem to be a "screen saver" function any more that I can see. just defining a slideshow for the lock screen. Is that the same thing????.

I defined the slideshow location as my /home/Pictures/ folder previously in Mageia #5.1 and it worked fine and my PC would show a nice photo for 20 seconds before showing the next one until I moved the mouse and had to enter my password on the lock screen. So, is this functionality still available in Plasma 5 or is it gone and been replaced by a "slideshow on the lock screen???

Anyway, my problem is the pictures were in the root of that Pictures folder. But in that /home/Pictures folder is a symlink called Pictures that points to an internal partition where my photos are located. When the screen locks it shows background wallpaper slideshow pictures from my photos library in the Pictures symlink, not the wallpaper slideshow of nice photos that I want but I can't find any way to delete/or modify this definition so it points to a newly created home/Pictures/Slideshow/ containing the nice photos that I would like to see in my screen saver/lock screen. I can define a new folder but that doesn't seem to help - I can't delete the original setting.
Any help/guidance appreciated.
