Deepin is an open source GNU / Linux operating system that preinstalls Deepin Desktop Environment (DDE) and almost 30 native Deepin applications, as well as several other open source applications to meet the daily learning and working needs of users.

In Deepin 15.9, many known errors and existing functions are optimized. Compared to deepin 15.8, deepin 15.9 adds support for touchscreen gestures and on-screen keyboard, optimizes the use of the frequency algorithm for the sequence of applications in Mini Launcher mode and introduces a new function: Smart Mirror Switch, with the hope to provide users with a more stable and efficient experience.

Since 15.8, a progressive upgrade strategy has been used to launch the updates on a regular basis. That is, deepin 15.9 is a summation of all those updates.


Multiple gestures

For touchscreen devices, multiple gestures are supported, including clicking, double-clicking, long-pressing to open the context menu, swiping up and down and others.

Working in conjunction with the new on-screen keyboard, you can enjoy operations on the touch screen.

Intelligent mirror

New function Smart Mirror Switch in the configuration of updates. Turn it on to automatically connect to the mirror site faster, which speeds up the download and installation to save time.

More convenient and efficient energy management

The easiest-to-use power management for laptops and desktops. Whether your computer is connected to the power supply or not, you can also easily change the monitor and computer suspend time for different scenarios.

other developments

  • The screensaver function was added in the system;
  • Deepin files adds support for Gif image files;
  • Images deepin is the default player for Gif images
  • Hibernate was added in the shutdown interface (it will only be shown if there is a SWAP partition).

Awesome, Love DEEPIN 🙂


And by the way, I do not know if it is an error, or not to use it but, tell me how to move the focus with the keyboard to choose the options. I used the arrow keys and the tabulator but I do not see the focus moving.
