Lightdm - Setting Enlightenment as Default

If you install Debian using LXDE installation image you'll find it's using the LightDM as a display manager. If like me, you use Enlightenment, you may want to set it as the default session.

First check the available sessions and see how they're named:

$ ls /usr/share/xsessions/
enlightenment.desktop     LXDE.desktop     openbox-gnome.desktop  XBMC.desktop

Conveniently the prefix for the Enlightenment session is named enlightenment, imagine that. We now need to tell LightDM that we wish Enlightenment to be the default. Using your favourite editor, open up /etc/lightdm/lightdm.conf and set user-session to:

user-session=enlightenment

Then you need to restart LightDM:

$ sudo service lightdm restart

When LightDM restarts, you should see Enlightenment set as the default session.
