Install Gnome 3.10 in Ubuntu 13.10 without breaking Unity

Solution 1:

I am currently trying out both, and installing Gnome 3.10 through the ppas you have listed does not break Unity. However Gnome 3.10 does not work perfectly for me, there are quite a few small but nagging issues (which are sort of expected). For example,

1) Brightness and gnome shell extension settings does not persist across reboots.

2) Nautilus (Files) seems buggy, it often freezes.

3) Gnome lock screen freezed a few times for me.

But Gnome 3.10 looks impressive overall, so you can give it a try (looks like you are interested).

I have installed Cinnamon 2.0 as well, and that in fact broke Unity. I can no longer login to Unity now, but Shell and Cinnamon work. There is actually an article on Softpedia that also points out the conflict between Unity and Cinnamon 2.0. I am not sure how to resolve the issue.
