Dear all,

I have imx6sxsabresd, yocto 4.1.0-2.1.0 from NXP.

i built image fsl-image-qt5

also qtwayland

weston works fine.

qml-compositor example does not work:

on running weston : 

unable to lock lockfile /run/user/root/wayland-0.lock, maybe another compositor is running.


without weston:

QXcbConnection: Could not connect to display : 0.0 







for qtwayland i copied :

<board dir>/tmp/work/cortexA9hf-neon-mx6sx-poky-linux-gnueabi/qtwayland/image/usr to <board>/usr/


could anyone help me please?

1- should i bitbake another image?

2- should i compile compositor and install it on board?

3- do i need specific environment variable? 

4- does qtwayland works for this distribution i have?


thanks a lot
