Plasma 媒體中心 - 技術預覽

Plasma Media Center is added as a tech preview in this release. It is fully stable but misses a few features compared to version 1. You can log directly into a Plasma Media Center session if you want to use it on a media device such as a television or projector or you can run it from Plasma Desktop. It will scan for videos, music and pictures on your computer to let you browse and play them.

Big Steps Towards Wayland Support

• Plasma 5.3 makes a huge step towards to supporting the Wayland windowing system in addition to the default X11 windowing system. Plasma's window manager and compositor KWin is now able to start a nested XWayland server, which acts as a bridge between the old (X11) and the new (Wayland) world. X11 windows can connect to this server as if it were a normal X server, for KWin it looks like a Wayland window, though. This means that KWin learned to handle Wayland windows in this release, though full integration is only expected for Plasma 5.4.

• In addition KWin gained new output modes for Wayland allowing to start a nested KWin on X11 and to start KWin directly on a framebuffer device, which will be the fallback for the case that OpenGL and/or kernel mode settings are not supported. A rendering backend on kernel mode settings is expected for Plasma 5.4. More information about these new backends and how to test them can be found in the KWin wiki pages. Please keep in mind that this is only a development preview and highly experimental new code.

Desktop Tweaks - Press and Hold

A new Tweaks configuration option in Plasma allows you to enable or disable the desktop settings toolbox and enable a new Press and Hold mode for widget management. In this mode, widgets can be moved after pressing and holding anywhere on the widget, and the widget handle will only be shown after press and hold rather than on hover. When this mode is enabled, unlocking the desktop will show a helpful instruction notification (which can be dismissed forever from the popup).
