Welcome to Q4OS

fast and friendly, desktop oriented operating system based on Debian Linux. Providing a set of dedicated utilities and specific optimizations, combined with a focus on getting a productive system easily.

Visual themes, Lookswitcher
would you like to change the default desktop look and feel ? Install Lookswitcher from the software center to get a few original desktop themes and a one-click tool to easily switch between them. Select a theme you like and enjoy the new desktop appearance.

Trinity desktop option
lightweight, fast, efficient, in many ways surpasses competition. In our opinion, a highly underrated desktop environment. Mainstream Linux distributions don't support Trinity at all, but we love it so much, that Trinity is even a dedicated download option, right after the default Plasma desktop.

Dual desktop ready
a unique alternative that makes possible setting up multiple desktop environments, typically Plasma and Trinity, side by side without interfering with each other. Carefully separated, ready to run as required, waiting for action. Just select the desired one at login time .. read more

Windows installer
an exclusive way to put Linux alongside Windows. Just run a setup wizard from within Windows and install Q4OS as easily as any other application. Although installed within windows, Q4OS kernel takes full control of the hardware. That is much more efficient than running a virtual machine .. read more
