So lightdm is doing something wrong imho: it's not "dereferencing" the default.desktop symlink to the real xubuntu.desktop, instead it's displaying two sessions as if they were distinct. Moreover, as it uses "default.desktop" as the key for the first session, all our xdg scripts are gonna break (because DESKTOP_SESSION=default instead of DESKTOP_SESSION=xubuntu will fill XDG_{CONFIG,DATA}_DIRS with incorrect paths).

(of course, I explicitly warned about this wrong behavior in another bug report when this feature was presented...)
