Package: lightdm
Version: 1.2.2-4
Followup-For: Bug #639984

Dear Maintainer,

we were bitten by that in a real environment, too. And, Yves-Alexis, you
were wrong when saying other login managers act equally.

I agree that when the lightdm binary is started directly it should somehow
be able to auto-detect if it runs in a nested environment or not.

Nonetheless we were using the runlevel startup scripts to restart lightdm over
a ssh connection which failed while other login managers (namely kdm) did
not. That way you can restart remotely any display manager I know of without
fiddling with the DISPLAY variable.

Thats why I ask you to accept this bug and maybe change the init script
accordingly in order to ignore the DISPLAY variable. If wanted, I can write up
a small patch which makes the behaviour configurable via /etc/defaults/lightdm.

With kind regards,
