[xubuntu] Session chooser

view story

http://ubuntuforums.org – Using Xubuntu 12.04.1 with the standard LightDM login screen, I'm offered the choice between two sessions at login. One is "Xubuntu session" and the other is "Xfce session" (I do not save sessions automatically at exit). However I see almost no difference in operation or appearance between the two. The only difference I've found is that "Xubuntu session" seems to stutter when starting the desktop. That is, I get the splash screen for about a second, then the monitor goes dark for a couple of seconds, then the splash screen comes back while the desktop initializes (Hardware)
