Hello Linux Geeksters. As you may know, XFCE 4.11 has been released a while ago. Also, the default window manager has been updated to Xfwm4 4.11.

Among others, Xfwm4 4.11 comes with an OpenGL compositor allowing the users to modify the transparency and shadows in some windows, support for Sync Black, which enables the users to import resizing and dragging window apps, some keyboard shortcuts fixes and other bug fixes.
In this article I will show you how to upgrade Xfwm4 to Xfwm4 4.11 on Ubuntu 13.10 Saucy Salamander, Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 16 Petra, Linux Mint 15 Olivia, Linux Mint 14 Nadia and Linux Mint 13 Maya, using the XFCE desktop environment.
$ 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
If you have issues with the Sync option, paste the following oneliner to your terminal and hit Enter:
$ xfconf-query -c xfwm4 -p "/general/sync_to_vblank" -s true
