Dear all,

I am currently using a i.mx6 Dual board on my task.

However when i do blanking: echo 1 > /sys/class/graphic/fb0/blank

the lvds display becomes smear, instead of turn blank (full black).


Is there anyway i can make the screen blank (full black), instead of the smearing when do blanking?


Thank you.
