Improve Plasma on touchscreen devices

Description

Touchscreen enabled devices (tablets and 2-in-1 notebooks) are becoming ever more prevalent in use cases that previously were occupied by traditional notebooks and desktop PCs. Currently no Linux DE (not even Gnome contrary to popular belief) works really well on tablets and 2-in-1s.

Every action a user might do in KDE Plasma should not be any harder than with a keyboard and mouse. The aim should be to reach Windows 10 level of UX on a touchscreen (if not even iOS on an iPad).

What it will take

  • Properly detect touchscreen devices and offer configuration options in System Settings
  • Make touch input a first class citizen in KWin (not just a simulated mouse click).
  • React to tablet and convertible specific events like switching rotation or entering tablet mode when the keyboard is flipped (Dell XPS 2-in-1) or disconnected (Surface Book)
  • Implement touch navigation (tapping, tap-and-holding, swiping, pinch-zooming, right-click) in all core KDE apps
  • Implement a dedicated tablet mode which deactivates the keyboard (if flipped on a 2-in-1) and makes UI elements bigger where necessary

How we know we succeeded

Entirely via touchscreen the user should be able to:

  • Boot into Plasma and log in
  • Customize the Plasma panels and plasmoids
  • Download Firefox from Discover
  • Suspend their session
  • Enter the session again
  • Download a PDF file from Firefox
  • Preview the file in Okular
  • Compose an email in KMail and attach the PDF file via finger drag-and-drop
  • Add a calendar event

These steps should be a doable on recent models of:

  • Dell XPS 2-in-1
  • Microsoft Surface and Surface Book
  • Lenovo Yoga
  • HP Spectre x360

It's also intertwined with T1154 about input methods, as one of the most important features of touchscreen interaction is a well working frustration free virtual keyboard

Unfortunately this goal wasn't selected as part of this round. If there is a critical mass of people who still want to push it forward please do! If support like financing a sprint is needed please reach out to the board.
Hopefully the selected Wayland goal will help make progress on this topic as well.
