That's not relevant. Your problem is that your settings aren't
being used because there isn't a real login, so something else has to
source .profile or equivalent. The last time I used KDM, it had a
bit of script to find the user's shell and source the appropriate files.
Your lightweight manager probably doesn't do anything at all about
this, so you have to do it yourself. Either put it where you have it or
look at the documentation for lightdm for an alternative place.
