See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Install Archlinux per https://wiki.archlinux.org/title/Installation_guide 2. Install SDDM per https://wiki.archlinux.org/title/SDDM 3. Install Plasma per https://wiki.archlinux.org/title/KDE#Plasma 4. Install Wayland per https://wiki.archlinux.org/title/Wayland 5.

After a short period, the underscore is replaced by a cursor in the middle of the screen (which does respond to mouse movement), followed very shortly by the reappearance of the greeter.
