[Pkg-xfce-devel] Bug#779076: lightdm: Fails to start when without recommended xserver-xorg metapackage

[Grant Sanders]

Package: lightdm
Version: 1.10.3-3
Severity: normal
Tags: patch

Dear Maintainer,


   * What led up to the situation?

I removed the xorg-xserver metapackage because all its dependencies were 
already manually installed or dependencies of other installed packages. I 
restarted my system and found the lightdm service unable to start.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

Looking at the logs indicated that dbus' inability to find service 
org.freedesktop.Accounts may be causing lightdm to refuse to create an X 
server. I tried all sorts debugging, but what worked was reinstalling
xserver-xorg and restarting the lightdm service.

   * What outcome did you expect instead?

I expected my fix to do nothing, but after trying many other things it seemed 
worth a shot.

So obviously the fix to the package is either to make xserver-xorg a hard 
dependency instead of a recommends, or to figure out why lightdm won't work 
without it. Nothing else complained about me removing the metapackage.
