Sabayon Linux 15.02 amd64 KDE.iso

Linux Kernel 3.12.5 with BFQ iosched, updated external ZFS filesystem support, GNOME 3.10.3, KDE 4.11.4, Xfce 4.10, LibreOffice 4.1.3, UEFI SecureBoot support for 64 bit images (with bundled UEFI shell), systemd as default init system, a greatly improved version of the Entropy package manager supporting concurrent activities (like parallel installation of applications) and PackageKit 0.8.x support with backend parallelization enabled. Last but not really least, the integration of Steam and a new install profile called Steam Big Picture mode (also improperly known as SteamBox on my blog) that turns your computer into a powerful Linux gaming machine.
These are just some of the awesome things you will find inside the box.
Familiar desktop environment, powerful applications
The beautiful desktop environment (see the screenshot above) is powered by the award winning KDE Plasma Workspaces and Applications project, which provides users with a modern, traditional, familiar and powerful graphical session that uses a single taskbar located at the bottom edge of the screen.

Launching applications, switching between the four virtual workspaces, interacting with running programs, as well as the system tray area is only possible with this semi-transparent taskbar of the KDE desktop environment.

Default applications include Chromium and Konqueror web browsers, Gwenview image viewer, Okular document viewer, KWrite text editor, Clementine audio player, K3b CD/DVD/BD burning tool, XBMC Media Center, VLC Media Player, Kopete instant messenger, Konversation IRC client, as well as Steam for Linux.

Additionally, it comes with the KOrganizer personal organizer, Marble virtual globe, Qt Designer UI builder, DNGConverter DNG image converter, Akregator feed reader, Klipper clipboard manager, KNotes note-taking utility, TiMidity++ MIDI sequencer, and Kontact PIM (Personal Information Manager) software.
Bottom line
Summing up, Sabayon Linux KDE is yet another astonishing edition of the well known Gentoo-based operating system, which can turn a high-end machine into a media center, dedicated gaming system, or standalone workstation.
