Linux and chill. Tweak and pimp. CentOS and Xfce. You thought you had enough CentOS in your life, haven't you? Well, no, Kemosabe, CentOS is like that professional wrestler and rapper, always coming back. Enough memes for one update yet. On a more serious note, here's a splendid guide explaining how to improve the look & feel and behavior of the Xfce desktop in CentOS 7.2, including visual tweaks like new icons, themes and decorations, transparent desktop icon text background, Whisker menu, keyboard shortcuts, system sounds, PulseAudio configuration, and more. Enjoy deeply.
