The Black Panther OS is a bare-bones Linux distribution built around the KDE desktop. The KDE environment itself is not a minimal component, but how it is integrated within Black Panther gives you an almost-nothing-there installation until you painstakingly install system tools and applications, literally piece by piece. Black Panther OS, originally forked from Mandriva Linux, is now under independent development in Hungary. Last month's version 16.1 release, dubbed "Silent Killer," marks the project's first use of the KDE Plasma 5 desktop.
