Plasma 5.5
Plasma 5.5

Tuesday, 8 December 2015. Today KDE releases a feature update to its desktop software, Plasma 5.5.


Video of Plasma 5.5 highlights

We have been working hard over the last four months to smooth off the rough edges, add useful new workflows, make Plasma even more beautiful and build the foundations for the future.


Breeze Icons
Breeze Icons

Updated Breeze Plasma Theme

The Breeze Plasma widget theme has been updated to make it more consistent.

While the Breeze icons theme adds new icons and updates the existing icon set to improve the visual design.

Plasma Widget Explorer

The Plasma Widget explorer now supports a two column view with new widget icons for Breeze, Breeze Dark and Oxygen

Expanded Feature Set in Application Launcher

Context menus in Application Launcher ('Kickoff') can now list documents recently opened in an application, allow editing the application's menu entry and adding the application to the panel, Task Manager or desktop. Favorites now supports documents, directories and system actions or they can be created from search results. These features (and some others) were previously available only in the alternative Application Menu ('Kicker') and have now become available in the default Application Launcher by sharing the backend between both launchers.


Color Picker Plasma Applet

New Applets in Plasma Addons

Color Picker

Not only have we restored support for the Color Picker applet, we've given it an entire new UI refresh to fit in with Plasma 5.

The color picker applet lets you pick a color from anywhere on the screen and automatically copies its color code to the clipboard in a variety of formats (RGB, Hex, Qt QML rgba, LaTeX).


User Switcher Plasma Applet

User Switcher

User switching has been updated and improved and is now accessible from the Application Launcher, the new User Switcher applet and in the lock screen. It shows the user's full name and user set avatar. This is very useful for offices with shared desks. More info in the developer blog.

Disk Quota

Plasma 5.5 sees a new applet designed for business environments or universities. This applet will show you usage assessed not around the real disk usage, but your allowed quota by your system administrator.

Activity Pager

Done for users whose use case of activities partly overlaps with virtual desktops: it looks like a pager, it behaves like a pager but uses activities instead of virtual desktops. This gives a quick glimpse of what activities are running and how many windows are associated to each activity.


Legacy Systray Icons
Legacy System Tray Icons

Restored Legacy Icons in System Tray Support

In response to feedback, we've rewritten support for legacy applications not using the StatusNotifier standard for system tray icons.

Bug Stats

In the run up to the Plasma 5.5 beta an incredible over 1,000 bugs were fixed.

OpenGL ES Support in KWin

Support for switching to OpenGL ES in KWin returns. So far only switching through an environment variable and restarting KWin is supported. Set environment variable KWIN_COMPOSE to 'O2ES' to force the OpenGL ES backend. Please note that OpenGL ES is not supported by all drivers. Because of that it's not exposed through a configuration mechanism. Please consider it as an expert mode.


Screen Locker

Wayland Progress:

With Plasma 5.5 a basic Wayland session is provided. Wayland is the successor of the dated X11 windowing system providing a modern approach. The system is more secure (e.g. key loggers are no longer trivial to implement) and follows the paradigm of 'every frame perfect' which makes screen tearing very difficult. With Plasma 5.4 the KDE community already provided a technology preview based on the feature set of the Phone project. With Plasma 5.5 this is now extended with more 'desktop style' usages. Important features like move/resize of windows is now supported as well as many integration features for the desktop shell. This allows for usage by early adopters, though we need to point out that it is not yet up to the task of fully replacing an X session. We encourage our more technical users to give it a try and report as many bugs as you can find.

A new screen management protocol has been created for configuring the connected screens of a Wayland session.

Also added are some protocols for controlling KWin effects in Wayland such as window background blur and windows minimize animation

Plasma on Wayland session now features secure screen locking, something never fully achievable with X. Read more about fixing this 11 year old bug on the screenlocker integration developer blog.

Please also see the list of known issues with Wayland on the Errata page.

Known Issues

Please see the Plasma 5.5 Errata page for some of the highest profile issues including some significant problems caused by Intel drivers.

Live Images

The easiest way to try it out is with a live image booted off a USB disk. You can find a list of Live Images with Plasma 5 on the KDE Community Wiki.

Package Downloads

Distributions have created, or are in the process of creating, packages listed on our wiki page.

Source Downloads

You can install Plasma 5 directly from source. KDE's community wiki has instructions to compile it. Note that Plasma 5 does not co-install with Plasma 4, you will need to uninstall older versions or install into a separate prefix.

Feedback

You can give us feedback and get updates on Facebook or Twitter or Google+.

Discuss Plasma 5 on the KDE Forums Plasma 5 board.

You can provide feedback direct to the developers via the #Plasma IRC channel, Plasma-devel mailing list or report issues via bugzilla. If you like what the team is doing, please let them know!

Your feedback is greatly appreciated.
