How to remove session entries from LightDM?
On Oneiric, I just installed a bunch of desktop environments / shells / windows managers by installing the kubuntu-desktop, xubuntu-desktop, lubuntu-desktop, e17 and gnome-desktop packages. Sometimes I enjoy a little variety, so I prefer to login to a random one each time I boot up. However, now the list of sessions I can choose from has close to 20 choices. I only want maybe five or six options, so most of them I will never use, e.g. Unity2D, or Xfce (I'd just use for the Xubuntu session). So I was wondering if there is a way to edit this list to only show the session I actually care about.
