PCLinuxOS, often shortened to PCLOS, is an x86-64 Linux distribution, with KDE Plasma Desktop, MATE and XFCE as its default user interfaces. It is a primarily free software operating system for personal computers aimed at ease of use. It is considered a rolling release.


The precursor to PCLinuxOS was a set of RPM packages created to improve successive versions of Mandrake Linux. These packages were created by Bill Reynolds, a packager better known as Texstar. From 2000 to 2003, Texstar maintained his repository of RPM packages in parallel with the PCLinuxOnline site. In an interview, Reynolds said he started PCLinuxOS "to provide an outlet for crazy desire to package source code without having to deal with egos, arrogance and politics."
In October 2003, Texstar created a fork of Mandrake Linux 9.2. Working closely with , Texstar has since developed that fork independently into a full-fledged distribution. The initial releases were successively numbered as "previews": p5, p7, p8 up to p81a, then p9, p91, p92, and p93.
Although it retains a similar "look and feel" to Mandriva Linux, PCLinuxOS has diverged significantly. The code was officially forked from Mandrake 9.2 into an independent project in 2003. After three years of continuous development, the developers took advantage of further development in Mandriva late in 2006 for PCLinuxOS 2007. In the releases before 2007, it was normally necessary to perform a re-installation.

PCLinuxOS 2007

For 2007, PCLinuxOS used a one-time source code snapshot from Mandriva to produce a new independent code base. This implied a shift to a more modern code, which required a complete reinstallation to this version. The new version featured a new look and built-in 3D effects. A new logo was also designed for the new version, and was incorporated into the boot screen. A new login screen was designed, entitled "Dark". The final/official PCLinuxOS 2007 version was released on May 21, 2007.

PCLinuxOS 2009

The last version of the 2009 Live CD, PCLinuxOS 2009.2, was released on June 30, 2009. Improvements included bug fixes, new backgrounds, sounds, and start-up screen, as well as quicker start-up times. It was the last PCLinuxOS live CD to ship with K Desktop Environment 3, and the last of the PCLinuxOS 2007 backward compatible series.
Remasters of PCLinuxOS, featuring the Xfce, LXDE, and Gnome desktops were also made available.

PCLinuxOS 2010

The 2010 version of the Live CD was released on April 19, 2010. It includes the new KDE SC 4.4.2, a new graphical theme and a new version of the Linux Kernel. It is also the first PCLinuxOS Live CD to include the ext4 file system support. This version required a complete reinstall of the operating system.
While a version of PCLinuxOS that features the GNOME desktop environment was introduced in 2008, the 2010 version is the first one to not only offer the KDE Plasma and GNOME versions, but also versions with Xfce, LXDE, Enlightenment, and Openbox.

PCLinuxOS 2010.1

Version 2010.1 was released on May 5, 2010. Changes made since last version:
PCLinuxOS 2011.6 version was released on June 27, 2011.

PCLinuxOS 2012

PCLinuxOS 2012.02 version was released on February 22, 2012. Later another maintenance release was made on August 22, 2012. Major changes compared to 2011 release are:
PCLinuxOS 2013 64-bit first version was released on April 10, 2013.
It featured:
The new version was released on July 7, 2014.
PCLinuxOS places specific emphasis on desktop computing, concentrating its efforts for home or small business environments, hence paying less attention to other more "traditional" uses, like servers, although packages for most server tasks are available.
PCLinuxOS is distributed as a Live CD, which can also be installed to a local hard disk drive or USB flash drive. Since version 2009.1, provides a USB installer to create a Live USB, where the user's configuration and personal data can be saved if desired. A live USB of older versions of PCLinuxOS can be created manually or with UNetbootin. The entire CD can be run from memory, assuming the system has sufficient RAM. PCLinuxOS uses APT-RPM, based on APT, a package management system, together with Synaptic Package Manager, a GUI to APT, in order to add, remove or update packages. If there is enough memory on the machine, and an active network connection, the Live CD can update packages. PCLinuxOS is also designed to be easy to remaster after installation, creating one's own personalized Live CD, using the mylivecd tool.
PCLinuxOS maintains its own software repository, available via the Advanced Packaging Tool and its Synaptic front-end, completely replacing Mandriva's urpmi. This means that an installation could be continuously updated to the latest versions of packages, hence sometimes forgoing the need to re-install the entire distribution upon each successive release. Other differences include its own menu arrangement, custom graphics, and icon sets.

End of official support for 32bit version

On May 10, 2016 main developer Texstar announced the end of support for 32bit versions of PCLinuxOS. As a result, 32bit ISOs of the distribution, official 32bit package updates and forum support ceased availability. While this doesn't prevent unofficial support, following the announcement only 64bit ISO images and package updates are available through the official webpage and channels.

Other versions

There are several community projects associated with PCLinuxOS.

KDE Fullmonty (FM) edition (Discontinued)

KDE FullMonty is a regular PCLinuxOS KDE installation, but is modified to include a special desktop layout and many additional applications and drives preinstalled. It is available as either a 32- or 64-bit edition.
FM applies a new concept: activity-focused virtual desktop layout, which is designed to address typical user-needs/tasks, make their life easy, and working on the computer straightforward and fun. It has 6 virtual desktops:
The idea of the FM concept is to provide the best out-of-the-box experience in an intuitive, thematically organized desktop setup. FM is designed for Linux beginners and newcomers from other operating systems. The typical user is provided with a cream of the crop selection of activity-related applications available in PCLinuxOS. The most popular ones are easily accessible from the respective virtual desktop and many more applications can be accessed from the PCmenu. The variety of applications in FM serves several purposes: advertising those applications to users; stimulating the comparative usage of these applications in the forum, learning about and discussing specific application features, and finally helping deciding on and providing constructive feedback on finding the most popular application for a given task. FM should facilitate the entry into the Linux desktop experience and provide an intuitive and easy to use working environment.

Trinity">Trinity (desktop environment)">Trinity edition

The Trinity edition of PCLinuxOS comes in 2 flavours, a mini-me that is a minimalist iso for those that want to customize their desktop with only the programs they want.
The Other is Big Daddy, which includes all the codecs for multimedia, office tools and more out of the box programs.

[LXQt] edition

[Xfce] edition

PCLOS community edition featuring XFCE desktop in a rolling release offers easy installation and setup, easy to update and works out of the box without systemd..a lot like MX-17 but non expiring. Bluetooth easiest working distro.

[MATE] edition

The newest edition of PCLinuxOS incorporates the MATE desktop environment, announced on the 3rd July 2013. PCLinuxOS Mate ISO is available in 64bit flavor only. These ISO is small enough to fit on a standard 700 mb CD or a small USB key.
Features: Mate Desktop 1.6.x, Kernel 3.4.52, Pulse Audio enabled by default, Udisks2, Hal daemon turn off but still available as a service if needed. All of the Mate desktop applications plus Firefox, Thunderbird, Pidgin and Skype. Clementine and VLC multimedia players. PysolFC for recreation.

Third-party distributions

Because PCLinuxOS includes the mklivecd script, there have been several third-party distributions over the years based on PCLinuxOS, though they may only mention that connection if they follow . Currently
is the premier example.
