If PATH is set on LightDM environment, it's propagated to the session login:

https://github.com/CanonicalLtd/lightdm/blob/master/src/seat.c#L383

On Debian we also patch it to make sure a PATH is set even if we don't have it
in the LightDM process environment, in which case we set it to the Debian
default (which includes /usr/games):

Hope that helps.
