Here is also a video with Gnome Shell in action:
sudo apt-get install jhbuild
Other Linux distributions: Please note that the script below should work on other Linux distributions too (some of them anyway). All you have to do is install jhbuild from your distro repository and then follow the steps below. Please note that looking at the script code, I can tell you for sure that these Linux distributions are supported: Ubuntu, Fedora, openSUSE and Mandriva.
Now that we installed jhbuild, we run the following commands to start the set-up:
wget http://git.gnome.org/cgit/gnome-shell/plain/tools/build/gnome-shell-build-setup.sh
bash gnome-shell-build-setup.sh
jhbuild build
Despite the simplification of the Gnome Shell installation process, the part of compiling it is not skipped - which will take a while, even for new computers.
After the installation is completed, we must run the following command to use Gnome Shell:
~/gnome-shell/source/gnome-shell/src/gnome-shell --replace
To update Gnome Shell to the latest version, open a terminal and paste this::
~/bin/jhbuild build --force --clean
