Hello Linux Geeksters. As you may know, XFCE is a popular lightweight desktop environment. The developers are still working at making XFCE 4.12 stable, which will come with new features, including optimizations for the xfwm4 window manager and a new background manager, which will automatically change the workspace’s wallpaper after a time specified by the user.
In this article I will show you how to install XFCE 4.12 on Ubuntu 13.10 Saucy Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal and Ubuntu 12.04 Precise Pangolin.
In order to successfully install XFCE 4.12 on the latest Ubuntu systems available, we have to add both the PPAs for XFCE 4.10 and XFCE 4.12 to avoid depencency issues, update the local repository index and install the xfce4 package. Like this:
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.10
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.12
$ sudo apt-get update
$ sudo apt-get install xfce4
If you already have a previous version of XFCE installed, add the two ppas and perform a system upgrade:
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.10
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.12
$ sudo apt-get update
$ sudo apt-get dist-upgrade
