Quark is a user-friendly operating system based on Ubuntu Linux with Plasma UI and built-in uniques tools of Q4OS distribution. The goal of the new distribution is to provide an Ubuntu-based operating system with the conveniences of Q4OS.
Unlike the Q4OS distribution, which is based on Debian, the Quark distribution is based on Ubuntu.
Another unique feature of Quark is its support for implementation of the extremely fast and efficient Trinity desktop alongside the default Plasma desktop. Just select Trinity in the Desktop installer and enjoy it once it's installed.
They are currently live pictures of the Quark distribution in two variants, which are essentially the same except for the default theme.
