For the longest time, Deepin Linux was based on Ubuntu. But with the release of 15.7, that all changed. Now, Deepin’s foundation is Debian, but the desktop is still that beautiful Deepin Desktop. And when I say it’s beautiful, it truly is one of the most gorgeous desktop environments you’ll find on any operating system. That desktop uses a custom-built QT5 toolkit, which runs as smoothly and with as much polish as any I’ve ever used. Along with that desktop, comes a few task-specific apps, built with the same toolkit, so the experience is consistent and integrated.
