[Pkg-xfce-devel] Bug#838610: lightdm-gtk-greeter: always uses the last session as default

Package: lightdm-gtk-greeter
Version: 1.8.5-2
Severity: normal

Dear Maintainer,

I run a number of computer labs, and use lightdm with the gtk greeter.
I haven't had time to patch the code, but have looked through the code.
Despite being able to configure a default session for ligthdm, once
lightdm has entered and exited a session it stores that selection in
its XDG_CACHE_HOME directory.  It then uses that saved session as the
default for the next time, overriding the default preference.

I can see where this might be an ok behavior in a home environment, but
in a lab environment it is problematic because users tend to expect the
same defaults every time rather than based on the last user.

(I've temporarily disabled this by making a link to /dev/null from
$XDG_CACHE_HOME/lightdm-gtk-greeter, preventing lightdm-gtk-greeter
from creating its state file.)
