Using the default login manager / greeter (sddm) which seems to support both X11 and Wayland. However i have to type my password at each startup, despite trying every way i can think of to get my session to start automatically on boot. Makes no difference which desktop/WM i last used: KDE (default), icewm etc.
sddm
to autologin is covered in many places; ie. disabling in the Lubuntu manual (manual.lubuntu.me/stable/3/3.1/3.1.8/sddm_configuration.html) or enabling it in questions (discourse.lubuntu.me/t/…) but I'd first check what you're using... ie. beta highlights you're months behind on security fixes & that is your major issue as I see it. (sddm
is shared by Kubuntu, Lubuntu & Ubuntu Studio with all the same in this regard)calamares
.... If you applied all security fixes you'll be using 23.04 &lsb_release -a
will say so, eg.Description: Ubuntu Mantic Minotaur (development branch)
on a alpha or beta for manticDescription: Ubuntu Lunar Lobster (development branch)
and not 23.04 (same occurs with alpha & beta... it changed to 23.04 when it reached RC or Release Candidate in the final days before release of Ubuntu 23.04 (& all flavors)
