I'm using light-locker as my lockscreen for my Arch Linux pc. Every time the lockscreen comes up there is this black white background image of a shoe store (seems to be the default). I really dislike it. Is there a possibility to set it to a random background image, preferably from some folder on my pc?
I don't know about your preferences for wallpapers but if you want I suggest you to try this GNOME extension. However, it goes without saying you must have GNOME shell on your Arch Linux.
