Plasma/Wayland Showstoppers

This page tracks the Wayland showstoppers through out the stack

General issues

NVIDIA

The NVIDIA blob is not supported as it uses a custom EGL extension. It would require additional code just for NVIDIA. On the other hand many users are on NVIDIA. Further information: To EGL Stream or Not and Plasma/Wayland and NVIDIA – 2017 edition

NVIDIA + XWayland

XWayland also uses the DRM/GBM mechanism. Due to that XWayland is not supporting OpenGL on NVIDIA even if KWin would support NVIDIA's eglstream. This would result in a terrible experience for all gamers.

QT_QPA_PLATFORM

QT_QPA_PLATFORM is set to wayland breaking any application which has Qt included (e.g. appimages, proprietary software) and doesn't have wayland QPA.

No remote support

We don't have an API yet for remote support. Even if we had things like TeamViewer would not work any more.

Input

No (wacom) Tablet support

KWin lacks integration the tablet support from libinput. Also KWayland lacks wrapping the API for it.

No configurable gestures

X has the ability to accept fake input events to allow programs such as Easystroke. With the new security model of Wayland, such a program would need to be part of the compositor.

No XModmap

We lack a functionality like XModmap to remap keys.

Plasma

Virtual Desktops

We don't have an API yet for virtual desktops, so pager is not working

No window thumbnails

We don't have an API yet for window thumbnails.

No window move on empty area in breeze

Broke with switch to XdgShellV6. Needs new API added to Qt (native interface), KWayland and Breeze.

Logout

There's a crash I know (but fixing properly breaks X). Might be more stuff with SDDM, needs investigation

No activities

Activities are probably not a must-have feature, but anyway this is annoying for those who got accustomed to them on X11.

Qt

No animated cursors

See QTBUG-48181

wl_proxy_create_wrapper

http://bugs.kde.org/381630

Key repeat not working

See QTBUG-55615

Compose key not working

Will be fixed in Qt 5.11, expected May 2018. See QTBUG-54792

No tablet support

QtWayland does not yet support the tablet API. So even if KWin had support Qt would not be able to use it.

Fullscreen does not work

see QTBUG-63748
