[Pkg-xfce-devel] Bug#869535: lightdm: service fails to start due to incorrect data dir perms

[Jonathan Lane]

Package: lightdm
Version: 1.18.3-1
Severity: important

Dear Maintainer,

The permissions on /var/lib/lightdm/data/ are root:root 755 instead of lightdm:lightdm 750 on install.  This breaks lightdm and renders the system unusable to anyone who doesn't know how to grab a shell via SSH or console TTY shifting.  A simple permissions change fixes it.
