Q4OS is a lightweight, Debian-based Linux distribution built for speed, stability and older computers. It ships with two desktops: the modern KDE Plasma, the default in the current Andromeda series, and the classic Trinity Desktop (TDE), a fork of KDE 3 with very low memory use.

The latest release, Q4OS 6.10 Andromeda, is based on Debian 13 “Trixie” (13.7). Get the ISO from the official download page.

System Requirements

Edition CPU RAM Disk
Trinity 350 MHz Pentium II or better 256 MB minimum 5 GB
KDE Plasma Any x86 or x64 processor 1 GB minimum, 2 GB recommended 5 GB minimum, 10 GB recommended

Trinity has long been available for 32-bit hardware, which is rare among current distributions. Check the download page for the architecture you need.

Key Features

  • Two desktops. Choose Plasma for a modern, customizable desktop, or Trinity for a traditional layout that runs on very old machines.
  • Desktop Profiler. Configure the system for different usage scenarios with predefined applications and settings.
  • Setup Utility. Install additional software and third-party applications from a graphical tool.
  • Welcome Screen. Shortcuts for common configuration tasks, software installation and documentation.
  • Familiar look. Windows-like layouts and themes help people switching from Windows. The XPQ4 tool goes further and gives Q4OS a Windows XP look (see the story below).
  • Debian stable base. You get APT, Debian’s repositories and about five years of support per stable series, and Debian guides generally apply to Q4OS as well.

Who Should Use Q4OS?

Q4OS is a good fit if you are:

  • Switching from Windows and want a familiar layout
  • Reviving an older laptop or desktop
  • Running a school, office or lab with mixed or aging hardware
  • A fan of traditional desktops who still wants current security updates

It is probably not the best choice if you want the very latest desktop software, since Debian stable favors reliability over novelty.
