PCBSD is a popular Linux Distribution based on FreeBSD. I just installed the latest PCBSD 10.0 on my VirtualBox on Windows 8 machine. I can get the full screen capability without having to install Virtualbox guest additions on PCBSD 10.0. The installation takes a while because there are many applications installed by default on this Linux distro. Here I want to show you the PCBSD 10 Joule screenshots with KDE desktop environment.
