As you may know, Google has created their own laptops for office work called Chromebooks, using ChromeOS as default. Also, an open-source ChromeOS-fork has been released, being called Chromixium OS.
Recently, the developer has renamed Chromixium OS into Cub Linux, the first RC version being recently released. Google has asked the OS developers to ditch the Chromixium name, due to copyright infringements, despite the fact that Google did not use the Chromixium name so far.
Cub Linux 1.0 RC1 is based on Ubuntu 15.10 Wily Werewolf, uses kernel 4.2 as default, but brings different artwork, to be similar to Google’s Chrome OS.
Cub Linux 1.0 RC1 is available for both 32 bit and 64 bit systems and has a dedicated repo for the in-house built packages. It uses Compton as the default desktop compositor, Parole media player has been replaced with Chrome Media Player, Clipboard daemon has been enabled, Viewnior has been used as the default image viewer, the Grub Bootloader Manager has been added to the Control Panel and the Chromium default apps and theme has been enabled by default.
