Build a wayland desktop by yocto

Wayland has been introduced as a replacement to the x11 for a long time but there is still a long way to go in the pc linux world.

I believe wayland will be widely used in embedded platform soon, because things like xserver use too many CPU time to do copy things, and ARM core are weak to do memory-copy things, compare to X86, which make a really bad performance.

Wayland have a modern desgin which make full use of GPU, so it have a more better performance than X11 in embedded platform. We should drop xserver now! (and fucking qte, minigui).


First, we should have a yocto sdk installed, and I use rockchip yocto sdk.

repo init -u -b yocto -m master.xml
repo sync
DISTRO=rk-wayland . ./setup-environment

Then, we need clone “meta-qt5-extra”.

git clone

And, include meta-qt5-extra and meta-gnome in bblayer.conf.

${BSPDIR}/sources/meta-openembedded/meta-gnome \
${BSPDIR}/sources/meta-openembedded/meta-initramfs \
${BSPDIR}/sources/meta-qt5-extra \

Add DISTRO_FEATURES_append += “ wayland pam x11” to local.onf.

Now, append liri-world to rk-image-machine-test and build it.

bitbake rk-image-machine-test

HAHA, after flash the rootfs created by yocto, I get a wayland based modern design desktop on rockchip platform! Faster than xserver!

Liri is based on Qt, which use gstreamer for multimedia, so the mediaplayer in Liri use hardware decode on rockchip platform by default.
