Hi,

We are developing a multi-display system using IMX6Q. We connected HDMI and LVDS display to Sabre SDB.

Bootargs used : video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666 ldb=dul0  video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24.

Now frame-buffer fb0 is HDMI and fb2 is LVDS.

 

Back-light of lvds screen gets turned off while blanking hdmi screen using command:

$echo 1 /sys/class/graphics/fb0/blank

 

Please help.

Regards,

Jayaram
