Hello. On the login screen after I switch users, I don’t get a prompt when I shutdown or reboot even though there is a logged in user. This is a fresh installation of neon that I performed last night from the following iso image: https://files.kde.org/neon/images/user/20240328-0716/neon-user-20240328-0716.iso
Plasma has a confirmation screen with a 30 seconds delay for shutdown/reboot/logout. This is very useful if the user presses the shutdown button by mistake. SDDM does not have that feature - so a single click on the shutdown button immediately shuts down the computer. This is not a serious issue if no one is logged in, but if there is a logged in account - everything still shutdown immediately which may even cause data loss - this just happened to me today where I lost unsaved text in Kate when I pressed shutdown by mistake in the SDDM switch user screen. I think it will be a good idea to have a confirmation dialog in SDDM for shutdown/reboot regardless if there are logged in users or not. BTW - I can't find SDDM in the production list.
Moving to the proper place Can confirm this behavior on current git-master. I agree it would be advantageous to have a timer on the user switch screen This can be considered in the next iteration of the login manager
