Plasma 5.12 LTS Beta Makes Your Desktop Smoother and Speedier

2018 年 1 月 15 日，星期一

Plasma 5.12 LTS Beta is the second long term support release from the Plasma 5 team. We have been working hard focusing on speed and stability for this release. Boot time to desktop has been improved by reviewing the code for anything which blocks execution. The team has been triaging and fixing bugs in every aspect of the codebase, tidying up artwork, removing corner cases and ensuring cross desktop integration. For the first time we offer our Wayland integration on long term support so you can be sure we will continue to fix bugs over the coming releases.

Plasma 5.12 LTS 新功能

更順、更快

We have been concentrating on speed and memory improvements with this long term support release. When Plasma is running it now uses less CPU and less memory than previous versions. The time it takes to start a Plasma desktop has been reduced dramatically.

Plasma on Wayland Now Under LTS promise

Plasma's support for running as Wayland is now more complete and is now suitable for more wide-ranged testing. It is included as Long Term Support for the first time so we will be fixing bugs in the 5.12 LTS series. New features include:

• Output resolution can be set through KScreen
• Enable/Disable outputs through KScreen
• 螢幕旋轉
• Automatic screen rotation based on orientation sensor
• Automatic touch screen calibration
• XWayland is no longer required to run the Plasma desktop; applications only supporting X still make use of it.
• Wayland windows can be set to fullscreen
• Uses real-time scheduling policy to keep input responsive
• Automatic selection of the Compositor based on the used platform
• Starts implementing window rules
• KWin integrated Night Color removes blue light from your screen at night-time; this is a Wayland-only replacement for the great Redshift app on X

For those who know their Wayland internals the protocols we added are:

• xdg_shell_unstable_v6
• xdg_foreign_unstable_v2
• idle_inhibit_unstable_v1
• server_decoration_palette
• appmenu
• wl_data_device_manager raised to version 3

Important change of policy: 5.12 is the last release which sees feature development in KWin on X11. With 5.13 onwards only new features relevant to Wayland are going to be added.

We have put a lot of work into making Wayland support in Plasma as good as possible but there are still some missing features and issues in certain hardware configurations so we don't yet recommend it for daily use. More information on the Wayland status wiki page.

Plasma 5.8 LTS 以來的新功能

如果您目前使用上一個 LTS 釋出版 (Plasma 5.8)，您可以期待許多新功能：

通知內的預覽

通知系統現在支援互動式預覽，讓您截圖後直接將它拖到聊天視窗、電郵撰寫工具，或瀏覽器的表單裡面。這樣您更不需要離開您目前使用的應用程式。

工作管理員改進

Due to popular demand we implemented switching between windows in Task Manager using Meta + number shortcuts for heavy multi-tasking. Also new in Task Manager is the ability to pin different applications in each of your activities. And should you want to focus on one particular task, applications currently playing audio are marked with an icon similar to how it’s done in modern web browsers. Together with a button to mute the offending application, this can help you stay focused.

全域選單

Global Menus have also returned. KDE's pioneering feature to separate the menu bar from the application window allows for new user interface paradigm with either a Plasma Widget showing the menu or neatly tucked away in the window title bar. Setting it up has been greatly simplified in Plasma 5.12: as soon as you add the Global Menu widget or title bar button, the required background service gets started automatically.

Spring Loaded Folders

Folder View is now the default desktop layout. After some years shunning icons on the desktop we have accepted the inevitable and changed to Folder View as the default desktop which brings some icons by default and allows users to put whatever files or folders they want easy access to. For this many improvements have been made to Folder View, including Spring Loading making drag and drop of files powerful and quick, a tighter icon grid, as well as massively improved performance.

鎖定螢幕上的媒體控制元件

在鎖定螢幕新增了媒體控制元件，在 Plasma 5.12 以上也可以為隱私停用它。另外，系統睡眠時也會自動暫停播放音樂。

新的系統設定介面

We introduced a new System Settings user interface for easy access to commonly used settings. It is the first step in making this often-used and complex application easier to navigate and more user-friendly. The new design is added as an option, users who prefer the older icon or tree views can move back to their preferred way of navigation.

Plasma 儲存庫

KDE has a focus on privacy. Our vision is: A world in which everyone has control over their digital life and enjoys freedom and privacy.

For users who often deal with sensitive, confidential and private information, the new Plasma Vault offers strong encryption features presented in a user-friendly way. It allows to lock and encrypt sets of documents and hide them from prying eyes even when the user is logged in. Plasma Vault extends Plasma's activities feature with secure storage.
