Booting into a “powersaving” version of Ubuntu
In this article I will explain how to boot into different environments with the same operative system (Ubuntu in this case) from the grub bootloader.
I wanted this setup to have an option in the boot menu to load a light and powersaving environment in my laptop, so I can use it on trains or air planes without AC outlet as long as I can.
Also you can use this setup to have, for example, a standard Ubuntu, a Media Center Ubuntu (using Elisa or XBMC), a Text Console Ubuntu (for maintenance duties), a GNOME Ubuntu, a KDE Ubuntu, etc…
