I just installed the Ubuntu 13.10 RC. Everything works fine so far.
The thing is i want to also install Gnome 3.10 and i worry that this will break Unity.
I know how to install the latest gnome release:
sudo add-apt-repository ppa:gnome3-team/gnome3-next
sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install gnome-shell gnome-shell-extensions
My question is if i should do anything else to ensure that i can have both environments without something breaking?
Edit
I followed the orders here so after the above steps i also did:
Switched to GDM
sudo apt-get install gdm
And select GDM instead of LightDM when prompted.
Removed the Ubuntu overlay scrollbars:
sudo apt-get remove overlay-scrollbar
