If you like to customize your XFCE desktop environment, you should use the new tool called XFCE Theme manager, which has a graphical user interface that allows you to easily customize your Xubuntu / XFCE DE.
XFCE Theme Manager allows you to customize the window borders, controls, icons, mouse cursors or change the wallpaper. It also has an advanced settings menu, for advanced users, let’s say, that enables you to change the team preview size (huge, large, medium or small), save the modifications you have created to the theme, install new theams by drag and dropping the tar.gz archives or reset the theme to its default settings.
In this article I will show you how to install XFCE Theme Manager on Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 15 Olivia, Linux Mint 14 Nadia and Linux Mint 13 Maya, all running XFCE.
To install XFCE Theme Manager on Ubuntu and Linux Mint you need to have the XFCE 4.10 repository added to your system. You can add it like this:
$ sudo add-apt-repository ppa:xubuntu-dev/xfce-4.10
Now that we’re all set, let’s install XFCE Theme Manager:
$ sudo add-apt-repository ppa:rebuntu16/other-stuff
$ sudo apt-get update
$ sudo apt-get install xfce-theme-manager
