    ArkOS

    ArkOS

    Another rockchip Operating System

    Another rockchip Operating System. This OS came about from an initial fork of The Retro Arena to support a roms folder on a NTFS partition so that the management of roms could be done by simply putting you SD card into an appropriate card reader on a Windows 10 computer. Through various upgrades and tweaks overtime, it has diverged significantly from TheRA and it's time to rebrand this distro. With suggestions provided by community members, ArkOS was chosen.

    Window Maker Live

    Window Maker Live

    Window Maker Live Linux Distribution

    Window Maker Live is an installable Linux Live ISO based on the current Trixie branch of Debian. The system uses the Window Maker window manager as the default graphical user interface. Window Maker Live's components have been carefully preconfigured and the desktop environment has a consistent visual appearance. Window Maker Live integrates selected components from other desktop environments such as XFCE4, MATE, LXQT, with a particular focus on GNUstep. The main idea behind this project is to integrate the Window Maker window manager as default user interface on top of a standard Debian/Trixie base system. It also serves as an alternate installation medium for Debian/Trixie. The second main idea not directly visible on the surface level is the inclusion of many useful command line utilities and tools for system administration. This effectively turns wmlive into a UNIX administrator's workbench for rescue and repair operations.

    HiddenVM

    HiddenVM — Use any desktop OS without leaving a trace

    If at any time Tails pushes an unexpected update, and HiddenVM is not yet updated for it, and you are stuck with a new Tails and no working HiddenVM version, you can re-download and temporarily use an earlier version of Tails until HiddenVM is updated. There are archived direct HTTP download mirrors of Tails images, archived official torrents with PGP signatures, or third-party archives at linuxtracker.org or fosstorrents.com, etc. (Always verify third-party torrents with archived official PGP sigs for safety.) Unless there is a known security vulnerability patched by the new Tails that actually affects how you use Tails, doing a temporary downgrade is not unsafe. You aren't necessarily unsafe by using older-than-one-month-old Tails software for a short time. Thank you for your patience, and stay safe.

    RebeccaBlackOS

    RebeccaBlackOS

    Fan Made RebeccaBlackOS. VT-less Linux With Wayland.

    I got the idea to name a Linux distribution after my favorite celebrity after I saw some earlier Linux distributions named after celebrities, and also this KDE blog post. http://ivan.fomentgroup.org/blog/2011/05/02/splash-screens-and-qml/ And then I thought, she deserves the free promo too. This is amongst the first live distributions to provide a Wayland server. VTs are disabled in the kernel. While 32 bit and 64 bit x86 ISOs used to be provided in each build, the latest builds are 64 bit only due to QtWebEngine refusing to build in 32 bit chroots. (It does NOT have her copyrighted music, or photos on the ISO. You have to buy her music legally on iTunes (or Amazon, etc))) The build scripts in the SVN is available for you to modify and build your own version of this project. This distribution is 3RD PARTY fan made. Yes. I am a fan of Rebecca Black. The latest ISO now has a login manager for Wayland, and now it has removed X from the startup path of the system.
