Embrace the dark side with Plasma 5.13: simple by default, powerful when needed
Plasma 5, the new generation of KDE's desktop has been developed to make it smoother to use while retaining the familiar setup. The Plasma 5.13 series is the default in this version of Kubuntu.
KDE Applications 18.04.3
Kubuntu comes with KDE Applications 18.04 containing all your favourite apps from KDE. Provided is the 18.04.3 update with bugfixes and translation updates. Most applications have been ported to KDE Frameworks 5 but those which aren't should fit in seamlessly.
Notable changes since 18.04 LTS
To ease the transition from legacy operating systems, double-click to open files and folders (select icons on first click) is now the default. To return to prior KDE defaults, use System Settings > Desktop Behavior.
Minimal install option
This is now available in the installer for Kubuntu.
For Kubuntu this removes KDE PIM applications, Libreoffice, Cantata and mpd, and some additional internet and media applications. At present a full Plasma Desktop is left in place, plus basic applications and utilities. Firefox as a browser, and VLC as a media player, are also retained.
The removal list will be reviewed and possibly amended for final release. Feedback to that end is welcome.
Plasma Wayland session - Available for testing, but not supported
A Plasma Wayland session is included for testing, but is not supported. Users needing a stable desktop experience should select the normal 'Plasma' (without Wayland) option at login.
