Hello Linux Geeksters. As you may know, Arch Linux is a bleeding edge Linux system that is among the first to receive the latest versions of the packages. While Ubuntu has a lot of third party PPAs, the Arch Linux users can usually get the latest versions of the packages via either the default repos or AUR (Arch User Repository).
Recently, one of the MATE desktop developers has created a repository containing Mate Desktop 1.9.1, built against GTK2 and GTK3 from the git master, helping the users to upgrade clearly from Mate 1.8 to 1.9.1.
So, to get Mate 1.9.1 (GTK2) on your Arch Linux system, you need to add the repository:
$ sudo sh -c 'echo "[mate-unstable-dual]" >> /etc/pacman.conf'
sudo sh -c 'echo "SigLevel = Optional TrustAll" >> /etc/pacman.conf'
sudo sh -c 'echo "Server = http://pkgbuild.com/~flexiondotorg/mate-unstable-dual/1.9/$arch" >> /etc/pacman.conf'
Next, upgrade the system and remove the obsolete packages:
$ sudo pacman -Syu
$ sudo pacman -Rs mate-dialogs
To install Mate 1.9.1 (GTK3) on Arch Linux, you have to add the same repository:
$ sudo sh -c 'echo "[mate-unstable-dual]" >> /etc/pacman.conf'
sudo sh -c 'echo "SigLevel = Optional TrustAll" >> /etc/pacman.conf'
sudo sh -c 'echo "Server = http://pkgbuild.com/~flexiondotorg/mate-unstable-dual/1.9/$arch" >> /etc/pacman.conf'
And upgrade and install the other needed packages:
$ sudo pacman -Syy
$ sudo pacman -S mate-unstable-gtk3 mate-unstable-extra-gtk3
