A while back I raised this topic How do I replace the lock screen?
I’ve tidied this up with a proposal that I would like your feedback with. This replaces the current lock-screen with slick-greeter i.e. consistent login and lock screens.
To try this out (20.04 only)
sudo add-apt-repository ppa:ubuntubudgie-dev/light-locker sudo apt upgrade sudo apt purge gnome-screensaver sudo apt autoremove
logout and login. Try locking the screen via the panel options/Super + L, suspend/resume, closing the laptop lid. There is a new light-locker settings menu option for controlling how the lock-screen works.
To reverse after testing is a bit more involved - so please follow the advice below exactly
sudo apt remove budgie-core sudo ppa-purge ppa:ubuntubudgie-dev/light-locker sudo apt install budgie-desktop-environment sudo apt autoremove
Logout and login.
