Unable to select other installed desktop environments when logging in.

[Alan Morgan]

I am using lightdm 1.3.3-0ubuntu4, in Ubuntu 12.10. I installed gnome-shell 3.5.92-0ubuntu1.

Gnome, Gnome Classic and Gnome Classic (No Effects) show up as selectable in lightdm as expected, along with Unity. However, Gnome Shell and Gnome Classic can not be selected. Clicking on them results in no response.

EDIT: I tried to see if the problem was the same with other desktop environments. It is possible to install and select xubuntu-desktop and use it properly. The buttons for selecting KDE and LXDE in lightDM respond visually to a click, unlike for Gnome Shell/Gnome Classic, but clicking on them does not result on them being selected.

Same problem here.

As a side-note: /etc/lightdm/lightdm.conf still had "gnome-shell" as default session, but there's no /usr/share/xsession/gnome-shell.desktop. The file has been renamed to gnome.desktop. However, fixing the wrong entry in /etc/lightdm/lightdm.conf had no effect on this bug. I'm just adding this note, because I suppose that there are more old/wrong references to gnome-shell that might cause this bug...
