Comment 3 for bug 1047894

I have the same problem, on a 12.04 installation. I installed Bluetile from the Software Center, and when I try selecting "GNOME + Bluetile" in the login window I don't get Bluetile, but just the standard wm. I think it's reverting to the default settings.

I think it might a problem with some of the files that are created when installing Bluetile, namely "/usr/share/xsessions/gnome-bluetile.desktop" and "/usr/share/gnome-sessions/sessions/gnome-bluetile.session". I have edited those files, so I can't really remember what they looked like, but will investigate further when I get time!
