Comment 19 for bug 1274740

@Matthieu, I was discussing this mitya57 the other day with respect to -flashback. it seems that it would be best to move the GNOME2/Compiz sessions to using "Unity", since that is far closer to the legacy environments that these sessions require. Things are just going to diverge further in the gnome3 land (for e.g. all legacy code will be dropped from g-s-d, g-c-c this cycle once the unity ports are complete).

There will be a few .desktop/autostart files that need tweaking but otherwise it should be straight forward to switch over.
