Bug#799325: weston: won't start despite having an active logind session

[Ben Longbons <brlongbons@gmail.com>]

Package: weston
Version: 1.8.0-3
Severity: important

Dear Maintainer,

According to README.Debian, having an active logind session should be
sufficient to start weston without being in the weston-launch group.

This does not work.

$ loginctl list-sessions
   SESSION        UID USER             SEAT            
       198       1000 ben              seat0           
         8       1000 ben              seat0           
       262       1000 ben              seat0           
       197        128 sddm             seat0           

4 sessions listed.
