Hi all!
When I change the SDDM theme via
System Settings > Colors & Themes > Login Screen (SDDM),
it works when I log out via Start Menu > Leave > Log Out.
But when I lock the screen using Super+L, it shows a different theme/interface — not the SDDM one I selected.
Why is the lock screen different from the login screen?
How can I make it so it useses the same theme?
I found Can’t change Background of SDDM? which is related, but it didn’t solve my issue.
Thx in advanced 
Hi @hux,
That’s as it should be.
SDDM handles the login.
kcreenlocker handles the lock screen. They are two separate packages that each need to be configured separately.
See here:
First, thx for the answer @Mirdarthos.
If that’s so, my next question is:
Why isn’t kcreenlocker theme an option in Colors & Themes just like SDDM?
I don’t know why.
Just that the lock screen theme follows the desktop theme.
But the lock screen image can be changed
under “Security and Privacy” → “Screen Locking” → “Configure Appearance”
Thx so much for the solution @Nachlese.
Sure some functionality may vary between SDDM and lock screen.
But it doesn’t make much sense to separate these to in my opinion.
Just plain confusion.
