Setting lockscreen wallpaper at startup.
Is there a way to set the wallpaper on the lockscreen at startup? I'm spanning a picture across two monitors with a third using a different image. On startup, at the lockscreen for my account before logging in shows only the primary display's wallpaper on all three monitors. Once I log in, the wallpapers are correct. Is there a way to have the changes persist through reboots or to be able to set the lockscreen's image to be used on startup?
