HDMI Screen blank after Torizon Os installation

Hi @AnuragBluAI !

Welcome to Toradex Community! Feel free to browse around! :smiley: :tada:

Are you using

Since you are on Mallow, you are using the X14 HDMI connector, which is the native HDMI. Currently, on Torizon OS 7, a bug on Weston container was found and it is being worked on.

A current workaround is to set WESTON_DISABLE_ATOMIC=1. For instance:

docker container run -d --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 253:* rmw"     --device-cgroup-rule="c 13:* rmw" --device-cgroup-rule="c 226:* rmw"     --device-cgroup-rule="c 10:223 rmw" --device-cgroup-rule="c 199:0 rmw" -e WESTON_DISABLE_ATOMIC=1 torizon/weston-imx8:4     --developer

Please note that this currently is just a workaround.

EDIT: There is another workaround, which involves removing the --current-mode from the entry.sh script of the weston container (torizon-containers/support-files/weston/entry.sh at stable ยท torizon/torizon-containers ยท GitHub) and rebuilding it. Although it is more work, I was informed that this a better approach from the technical point of view.

Best regards,
