Hi, > in my case i thought that plasma would pop up, but fluxbox appears
Confirmed. The reason is that sddm 0.19 changed the format of the file /var/lib/sddm/state.conf in that the Session contains only the relative path, not the absolute. Old (0.18) had Session=/usr/share/xsessions/plasma.desktop New (0.19) has Session=plasma.desktop Let us see whether we can fix that automatically.
