Plasma/Wayland

On this page, we're collecting tips and tricks to make Plasma work on Wayland:

Build instructions

We recommend following this guide to install the Wayland stack, including the QtWayland module

• http://qt-project.org/wiki/QtWayland

Generic, but more detailed build instructions for Wayland / Weston, including underlying stack can be found at: http://wayland.freedesktop.org/building.html

Create a wl-env script somewhere in your $PATH, looking like this (adjust WLD to your wayland installation path):

WLD=/home/sebas/kf5/wayland/install
LD_LIBRARY_PATH=$WLD/lib
PKG_CONFIG_PATH=$WLD/lib/pkgconfig/:$WLD/share/pkgconfig/
ACLOCAL="aclocal -I $WLD/share/aclocal"
export YACC=bison

# This is needed for now, as kscreen will otherwise pick the XRandR backend -- and crash
export KSCREEN_BACKEND=fake

export WLD LD_LIBRARY_PATH PKG_CONFIG_PATH ACLOCAL YACC

if test -z "${XDG_RUNTIME_DIR}"; then
    export XDG_RUNTIME_DIR=/tmp/${UID}-runtime-dir
    if ! test -d "${XDG_RUNTIME_DIR}"; then
        mkdir "${XDG_RUNTIME_DIR}"
        chmod 0700 "${XDG_RUNTIME_DIR}"
    fi
fi

Running KF5 applications under Wayland

Inside an existing X session

weston

starts a new window under your X server with Weston running inside it.

Standalone

From a hard console / virtual terminal:

kf5-env
wl-env
export $(dbus-launch)
weston-launch
kwrite -platform wayland

kf5-env is a script setting up the locations, such as QTDIR, plugin path, etc. for your kf5.

Issues

The following contains a list of issues found when trying to run Plasma or KF5-based software in general under Wayland.

• kdeinit5 exits due to missing DISPLAY
• kded5 just hangs there when started
• Oxygen style works in windowed mode, falls back to Fusion in standalone
• File open dialog unable to reach klauncher
• After resizing a window, it's not immediately repainted over the new covering area
