VNC setting issue

Hi

I am encountering VNC issue.

My set is Verdin-Plus and Development Board connected to 2 displays under TorizonCore OS.
Torizon(BSP) version is 5.4.193-5.7.0+git.f78299297185.
1st display is LVDS-1: 10"capasitive-touch LCD[1280x800] connected via Verdin DSI to LVDS Adapter.
2nd display is HDMI-A-1: HDMI display[1280x1024] connected via Native HDMI port.

VNC works fine with the below command which bind-mounts weston.ini to weston. Only 1st display is cloned to VNC client on PC. (Despite of --developer, weston.ini is effective…)
$ docker run -e ACCEPT_FSL_EULA=1 -e ENABLE_VNC=1 -d --rm --name=weston --net=host -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ -v /home/torizon/weston.ini:/etc/xdg/weston/weston.ini --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:2 --developer weston-launch --tty=/dev/tty7 --user=torizon

VNC does not work with with the below command which bind-mounts weston.ini to weston-dev.
$ docker run -e ACCEPT_FSL_EULA=1 -e ENABLE_VNC=1 -d --rm --name=weston --net=host -v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ -v /home/torizon/weston.ini:/etc/xdg/weston-dev/weston.ini --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:2 --developer weston-launch --tty=/dev/tty7 --user=torizon

Could you kindly help and advice to make the latter work fine?

Thanks and regards

Hi @ujsugi ,

Can you verify that your weston.ini has the following line on section [core]:

modules=screen-share.so

If this line is not present then VNC will not be enabled on Weston. It should work if this line is present and if ENABLE_VNC is set to 1, which you already did.

If you pass the --developer option in our image Weston will only read the config file located in /etc/xdg/weston-dev/. In your first scenario you bind mounted the .ini file to /etc/xdg/weston/, so Weston read the default weston.ini in /etc/xdg/weston-dev/, which has the line above.

Try that and let me know if it works.

Best regards,

Thanks for quick response.
It’s working fine by adding the follows in weston.ini.
[core]
modules=screen-share.so.
Plus, weson.ini appear to be bind-mounted to /etc/xdg/weston-dev/ correctly.

Thanks and regards
