Absolute is a 64-bit Linux distribution based upon Slackware. It concentrates on "desktop" use so that it is ready for internet, multimedia, document and general home use out of the box. Absolute is lightweight -- meaning 2 things: that it can run on on modest hardware and that the OS interface stays out of your way... but includes the latest software like: Kodi, Inkscape, GIMP, LibreOffice, Google Earth, Google-Chrome, Calibre, etc.
It is version-compatible with Slackware so you can use almost any package from the same version of Slack on Absolute. Development libraries (headers) for everything installed are always included, so you can code and/or build almost anything from source.
About Absolute Linux
Is a modification of Slackware
Fast, stay-out-of-your-way desktop. No Gnome or KDE. Uses well integrated collection of the best lightweight software to give you most of the things the "big desktops" give you, only at at much, much faster pace.
The software folks use on a desktop: Firefox, OpenOffice, Pidgin chat, GIMP image editor, WPClipart, Thunderbird mail, K3B CD/DVD burning, Frostwire P2P, Deluge BitTorrent, 2 dictionaries, a bunch of games -- basically any of the latest, most popular Open Source software.
Many script utilities (with friendly little GUIs) to make configuration and maintenance of system easier and still allows manual (text-file based) configuration, if desired.
Package compatible with Slackware minor versions. (ex. Absolute 12.2 -> Slackware-12.2), with a few exceptions: kernel packages, KDE-libs, madwifi, ndiswrapper, svga-helper, a/etc.
Root user can install software or set system configurations. That's it. Perfect for parents and IT guys. If you want to do something root user is allowed to do, log in as root. That's what the account is for.
