Hi there. I upgraded my lubuntu distribution from 12.10 to 14.04. Something got broken in the process and now when loging in with my user to lubuntu environment i have no desktop nor lxpanel. When running lxpanel the panel shows up, but with none of my settings. When loging in lubuntu netbook environment everything is fine. I installed lxde meta package and when loging in lxde everything is fine too (but with default settings, of course).
when loging with other users in lubuntu environment everything is fine for those users, so i would say something is broken in the process of loading my lubuntu environment.
