Good afternoon.
Using Mageia 8 beta KDE (and, before that, Mageia 7 with no problems whatsoever). I haven't applied updates in a while.
Yesterday I changed the default login theme in KDE system settings (Workspace --> Startup and Shutdown --> Login Screen (SDDM)) from default Mageia theme to some other. It asked for root password, I successfully applied it and closed settings.
Today, as I turned on the computer, it succesfully boots but there's no login screen, only a black screen with cursor. This is the only change I've done recently. Apart from that, everything has been very stable.
How can I restore default login theme and, hopefully, solve this problem? I can access Ctrl+Alt-F2.
Many thanks. Mageia is my favorite distro.
