I have build an Ubuntu remix with UCK, Ubuntu Customization kit and have installed Cinnamon via PPA. Now I want the Live DVD to start with Cinnamon directly. How to do this ? Terminal command maybe ?
It seems that the installation is on hard disk and you want to run Live CD/DVD in cinnamon.
To run the Live CD and fetch Cinnamon from installation is, I would say, tricky. But it is still possible to get Cinnamon on Live boot:
3) Install cinnamon now.
4) Log out, put your username there (whoami one), and from the menu (Gear in 11.* and 12.* while bottom of the page list for older versions), select "Cinnamon" instead of "Gnome"
5) Enjoy :)
