Weston terminal on wayland app does not start on 10 inch LVDS screen

Technical Support

I am following the instructions noted below to start the weston terminal on the wayland app.
I am using a Verdin imx8mplus on the Verdin board with a verdin mezzanine card connected to a 10.1 inch capacitive LVDS display.

On power up, I can see the Torizon image on the LVDS screen, indicating that connections are ok.

However, I am unable to see the weston terminal as noted from the instructions on the LVDS screen. Please can you check.

See log below of the commands used.

Hi @SJ_BHD , thanks for contacting us :smile:

We refactored some things with the Weston container for TorizonCore 6 and it looks like that specific part of the documentation did not get updated. Thanks for noticing, we’ll update it as soon as possible.

To accomplish bringing up Weston you can run the following:

docker run --rm -e ACCEPT_FSL_EULA=1 -v /dev:/dev -v /dev/galcore:/dev/galcore -v /tmp:/tmp --device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' --device-cgroup-rule='c 4:0 rmw' --device-cgroup-rule='c 4:7 rmw' --device-cgroup-rule='c 4:1 rmw' --cap-add=CAP_SYS_TTY_CONFIG torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE --developer

or use this handy docker-compose.yml file:

version: "2.5"
services:

  weston:
    image: torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE
    # Accept the EULA required to run imx8 vivante graphic drivers
    environment:
     - ACCEPT_FSL_EULA=1
     - ENABLE_VNC=1
    # Required to get udev events from host udevd via netlink
    network_mode: host
    volumes:
      - type: bind
        source: /tmp
        target: /tmp
      - type: bind
        source: /dev
        target: /dev
      - type: bind
        source: /run/udev
        target: /run/udev
    cap_add:
      - CAP_SYS_TTY_CONFIG
    # Add device access rights through cgroup...
    device_cgroup_rules:
      # ... for tty0
      - 'c 4:0 rmw'
      # ... for tty7
      - 'c 4:7 rmw'
      # ... for tty1
      - 'c 4:1 rmw'
      # ... for /dev/input devices
      - 'c 13:* rmw'
      - 'c 199:* rmw'
      # ... for /dev/dri devices
      - 'c 226:* rmw'
    command: --developer

save as docker-compose.yml inside TorizonCore and run docker-compose up in the same path.

Thanks for coming back so quickly. I ran the docker command on the bash terminal, can see a grey screen now. However dont see a terminal. See log below.

Hi, thanks for the logs. Can you confirm which version of TorizonCore you are using?

If it’s TC5, you should refer to this thread: Weston-vivante:2 launches differently - #2 by jeremias.tx

The screen you should be seeing is the full weston desktop.

However dont see a terminal.

In TC6 it’s currently not possible to launch the terminal directly, but I’ll raise this need internally with the team.

Regards,

Hello @SJ_BHD ,
You are using TorizonCore 5 so the info in the thread that @leon.tx mentioned should work for you.

Please let us know the outcome.

Best regards,
Josep
