[Hendrik Lehmbruch <hlehmbruch@gmx.net>]

Package: sddm
Version: 0.19.0-1
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
upgrading sddm

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
reboot and login, now 3 times

   * What was the outcome of this action?
in my case i thought that plasma would pop up, but fluxbox appears

   * What outcome did you expect instead?
i would like to see a plasma-session (last-session) with out choosing it after
every reboot/logout and not the first in the line (fluxbox in my case)
