Hello Linux Geeksters. As you may know, Mate is a Gnome 2 fork, specially developed by the Arch Linux developers, in order to provide their users an alternative to Gnome 3. Because it is a nice and stable desktop environment, Mate has been ported to many of the most important Linux systems, including Ubuntu, Fedora or Debian.
Recently, Mate 1.6 has been added to the default repositories of Arch Linux, so installing it is very easy.
To install only the Mate desktop environment, on an up to date system, just do:
$ sudo pacman-Syy mate
For installing Mate and the extra packages, do:
$ sudo pacman-Syy mate mate-extra
Also, if you are a netbook user, you can install the Mate desktop specially optimized for netbooks:
$ sudo pacman-Syy-mate netbook
