Hi @jrocher ,

Concerning the weston-vivante container, I started qt5-wayland-vivante:2 , it should also work right ? I think I actually also tried with the weston-vivante one and faced the exact same problem.

The applications inside qt5-wayland-vivante:2 should only work if weston-vivante:2 is up and running. Just to be sure, try doing the following:

  1. Stop any running containers with docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q)

  2. Start weston-vivante:2 with this command:

docker run -e ACCEPT_FSL_EULA=1 -d --rm --name=weston --net=host --cap-add CAP_SYS_TTY_CONFIG \
             -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ \
             --device-cgroup-rule='c 4:* rmw' --device-cgroup-rule='c 13:* rmw' \
             --device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' \
             torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE --developer weston-launch \
             --tty=/dev/tty7 --user=torizon

You should see a graphical desktop-like environment on your display after this command. If that’s not the case, then something is wrong with the Weston container and the QT apps will not work.

  1. Start the qt5-wayland-vivante:2 container as you did before:
docker run -e ACCEPT_FSL_EULA=1 --rm -it --name=qt5 \
           -v /tmp:/tmp \
           -v /dev/dri:/dev/dri -v /dev/galcore:/dev/galcore \
           --device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' \
           torizon/qt5-wayland-examples-vivante:$CT_TAG_QT5_WAYLAND_EXAMPLES_VIVANTE \
           bash
  1. Inside the container, try executing any of the sample applications:
/usr/lib/aarch64-linux-gnu/qt5/examples/quick/animation/animation &

Doing the steps above I was able to run the sample apps without any problems on a Colibri iMX8X with TorizonCore 5.7.0.

See if the error persists when doing the procedures mentioned above.

Best regards,
