Ubuntu 16.04 LTS adopts the long-supported Linux kernel, and the version number is 4.4. Compared with the general kernel, this kernel will get security updates and BUG fixes for a long time. Moreover, after the life cycle of Linux kernel 4.4 LTS ends, Canonical will continue to provide support until Ubuntu 16.04 LTS ends to 202 1.
In the report just now, we have provided many system screenshots of this new system. From the appearance of the system, it has not changed much, but only slightly adjusted the icon and Unity interface-it can be integrated with file managers and devices, and provide support for GTK applications using headerbar.
Switches and propagation backend have also been improved. Users can use the Super+Ctrl+W hotkey to activate application propagation, and the Unity Control Center option always displays the menu. There is also a new Unity Dash overlay scroll bar and better Unity Dash theme support. By default, online search in Dash is turned off.
This time, the new system also adds the support of scaling mouse pointer in HiDPI environment with Unity interface, and it seems that the login manager also has better support for HiDPI. Unity can also display the startup status of icons in Launcher when each application is started in different workspaces, and now it can also move Unity Launcher to the bottom of the screen.
The latest versions of system components are as follows: LibreOffice 5. 1.2, Mozilla Firefox 45.0.2, Python 3.5, OpenSSH 7.2p2, PHP 7.0, MySQL 5.7, GCC 5.3, Binutils 2.26, Glibc 2.23, Apt 1.2, Da. Students who have been upgraded can check it.
All pre-installed packages are switched to the WebKit2 engine. Ubuntu 16.04 LTS is also the first Ubuntu version that no longer contains Ubuntu Software Center (originally provided by Canonical), and is replaced by GNOME software application from GNOME Stack, but it is called Ubuntu software in this version of the system. In addition, by default, the GNOME calendar is included in the system, while the Brasero and Empathy applications are deleted.
Canonical said: "fglrx driver has been abandoned in 16.04, and we suggest adopting open source alternatives (radium dragon and AMD GPU). AMD has done a lot of work on drivers, and we also transplanted the kernel code backwards from Linux 4.5 to provide a better experience. After upgrading from the previous version to Ubuntu 16.04, both fglrx driver and xorg.conf will be removed, so the current system adopts AMDGPU driver or radium dragon driver (depending on the available hardware). "
Finally, the new system began to support the installation of snap package, which supports more languages by default.
