i upgraded last night! and when i booted up this morning, i was unable to log into any accounts in the login screen lol. if anyone else has a similar issue where the only option login screen gives you is wayland and that doesnt work for you or you want to use x11, what fixed it for me was installing plasma-meta as for whatever reason that wasn't on my system at the time. this allowed me to select x11 again from the login screen and my system is working as normal.
i know we're still in early days of plasma 6, but does anyone know any good calendar/weather/time widgets that i can replace this one with? https://store.kde.org/p/998901/ haven't found another good calendar widget yet.
