Hello, I am developing an (embedded) medical device which is required to have a touchscreen display and also mirror the output to a monitor connected via HDMI. The device is using Wayland/Weston on TorizonCore (based on a yocto kirkstone). I am able to get the display extended from HDMI to LVDS, but not have the output mirrored to both displays. I posted a query on the Toradex community, and received a response that Weston may not be capable of doing this. (https://community.toradex.com/t/apalis-imx8-hdmi-and-lvds-display-not-mirroring-cloning/19869).
I have searched and found some old posts from several years ago indicating that it was not supported, but may be with a patch. I understand that "same-as" configuration in weston.ini does not work for my scenario. What is the current state of cloning/mirroring to two different outputs, but on the same card. E.g (card1-HDMI-A-1 and card1-LVDS-1): ls /sys/class/drm card0 card1 card1-HDMI-A-1 card1-LVDS-1 renderD128 renderD129 version Thanks, Dawn The information contained in this e-mail and any attachments are intended solely for the addressees.
