      I configure imx6qp with g2d can display two screen normal in weston clone mode. like below:

     # /etc/init.d/weston stop

     # weston --tty=1 --use-g2d=1 --device=/dev/fb0,/dev/fb2 --clone-mode --log=/var/log/weston.log


      I found if I configure weston two screen display with g2d ,first will found blue screen ,later display the weston lauch.

 And the weston cannot lockscreen and standby.

       If I configure weston single screen display with gl,the --idle-time=300,default 5min,start the weston ,first is black screen,later is display the weston lauch.5minute later will lockscreen,screen off .

Why configure weston display with g2d,first start the weston will found blue screen,not black screen,this is not good for me.And configure idle-time is not valid.


Anyone can help me solve this problem or give me some advices?
