Hi All,

we are working dual display on IMX8QM platform with Yocto Linux (L5.10.52). We able to achieve dual display working as extended display but it is not working as independent displays

Following commands I have executed plays the video in primary display

gst-launch-1.0 filesrc location=file1.mp4 ! video/quicktime ! qtdemux name=d d. ! queue ! h264parse ! v4l2h264dec ! imxvideoconvert_g2d ! waylandsink &

To play video on to other (secondary/extended) display need mouse pointer/cursor moved to the second display before playing the above gstreamer. Is it possible to dedicate two touch to each of the display since we have use case to support two independent operating the two displays

We could achieve independent display with QT but we would like to do the same with native wayland/weston compositor

Hi @vinothkumar

Welcome to Toradex community.
Could you provide the hardware and software versions of your setup? Also, What displays combination are you using like LVDS+hdmi?

Thank you for the reply,

We are using IMX8QM with Yocto OS (Linux 5.10.52) which is under Wayland distro and we are trying for MIPI or LVDS display combination.

Hi @vinothkumar

Are you using the IMX8QM MEK and NXP BSP? if yes, we are not supporting NXP BSPs.
