deepin is a Linux distribution devoted to providing beautiful, easy to use, safe and reliable system for global users.
deepin 15.7 mainly optimizes the performance, including ISO size reduction, laptop power optimization and memory optimization. What is more, it fixed many bugs found in deepin 15.6.
Starting with version 15.7, deepin will adopt new version number and new upgrade strategy: the version number format is x.y.z. X is the main version number, and the current main version number is 15, which means this version is developed and maintained from 2015; y is the subversion number, usually updated every three months; z is a minor version number, if there are important system updates between the two x.y versions, 1 or 2 minor versions may be released. The version y with even number will have more feature updates, while the version y with odd number will focus on system optimization and stability enhancement.
Therefore, deepin 15.7 will be the first version to focus on system optimization and stability fixes under this rule. Note: deepin 15.7 fully synchronizes the latest repository components of upstream Debian, so if you upgrade from an earlier version (including 15.6) to 15.7, you will receive more than 1G updates. This process, depending on your Internet bandwidth, may be as short as 10 minutes and as long as hours. Please wait patiently for the full upgrade, do not shut down or unplug the power during the process, otherwise you may not be able to enter the system.

ISO size reduction

As deepin family continues to grow with more and more functions, deepin ISO size is constantly increasing. By ensuring the core functions, in deepin 15.7, the pre-installed applications, wallpapers, fonts, videos, etc. have been adjusted to remove unnecessary components and optimize system structure. By this way, deepin 15.7 ISO size is reduced to 2.5G, much less than that of deepin 15.6 with 3.1G.

The ISO size comparison of deepin 15.7, deepin 15.6 and other operating systems are as follows:

Laptop power optimization

To reduce power consumption of laptop, "power saving mode" is added in deepin 15.7. Your laptop can enter power saving mode automatically when using battery. In this way, laptop standby and working time is increased. Preliminary tests show that in our test environment, standby time is extended 20%.

Memory optimization

deepin 15.7 has made a series of adjustments and optimizations in memory usage. In the standard configuration, the boot memory has decreased from 1.1G to 830M, and reduced to less than 800M on a discrete graphics card. The memory occupation comparison of deepin 15.7, deepin 15.6 and other operating systems on the same computer are as follows:

Adjustments and optimizations for other functional modules have been made as well, the new features are as follows:


  • Added OSD when turn on/off microphone/WIFI;
  • Added the animation when drag and drop icon from dock;

Control Center

Added power saving mode and auto mode switching function for laptops;

    • Added the time-costing prompt when there was a big upgrade;


    • Added application categories in mini mode;
    • Supported using Tab key to jump between different areas;


    • Added full disk installation; it automatically divides the disk into a reasonable swap partition to support system hibernation, a /home partition and an independent /data partition for users to restore personal data when reinstall;
    • Added the animation in login and unlock password box;
    • Added NVIDIA-PRIME solution for laptops with hybrid graphics.



    • Rebuild network plugin;
    • Optimized the animation when opening an app on dock;
    • Optimized preview on dock;
    • Optimized plugin loading mechanism;

Control Center

    • Optimized the scrolling effect in Control Center;
    • Optimized system volume;


    • Optimized the switching effect between workspaces;


    • Optimized the login animation;
    • Optimized the display of keyboard layouts;
    • Google Chrome was updated to the latest 68.0.3440.84-1 version;
    • Firefox Quantum (ZH) was updated to the latest 61.0.2-1 version.

Bugs fixed

    • Fixed the memory leakage caused by switching wallpapers;
    • Fixed the deadlock issue of the property window in File Roller;
    • Fixed icon loss in Launcher;
    • Fixed the bug that no keyboard layout was shown on greeter interface;
    • Fixed the wrong partition number shown in Deepin Installer;
    • Fixed the bug that notifications were hidden when show desktop;
    • Fixed the bug that the login password cannot be input after waking the computer;
    • Fixed the confusion of Intel Compatible Mode and Intel Acceleration Mode in Deepin Graphics Driver Manager;
    • Fixed the blank OSD when adjusting volume and brightness;
    • Fixed the wrong notification location (bottom right corner) when recovering from suspend mode;
    • Fixed the drag and drop issue in Deepin Font Installer;
    • Fixed the incorrect memory info in Deepin System Monitor.Internal test conclusion
      Prior to deepin official release, usually an internal test is implemented among a small number of community users, then we record their feedbacks and fix the bugs. Before deepin 15.7 release, internal upgrade test and public ISO installation test are carried out.
      In this release, we would like to thank all the internal testing team and the community users.
