imx6qp qt5 wayland dual screen display with g2d first bluescreen problem in yocto bsp 4.1.15-2.1.0-ga

[mrleo]

Hi,all

      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?

Thanks,

Leo

If you view the weston codes,you will find the reason of blue screen: in raw codes of ./libweston/g2d_renderer.c,all .clrcolor=0xFF400000;

I change the value to 0x0(means black).
