My board is imx6dl sabresd board, I tried a lot to make LVDS + WVGA dual diaplay successful, but I failed ,
Is there anyone can give me some advice?
the VGA of my board is from DISP0(RGB24 interface), I had already successfully used VGA as single display screen with
uboot bootargs : console=ttymxc0,115200 init=/init video=mxcfb0:dev=lcd,1280x720M@60,if=RGB24,bpp=32,
and I also had had HDMI +LVDS by using uboot bootargs :console=ttymxc0,115200 init=/init rw video=mxcfb0:dev=ldb,1024x600M@60 video=mxcfb1:dev=hdmi,1920x1080M@60 video=mxcfb2:off fbmem=10M,28M vmalloc=512M fb0base=0x27b00000
but when I wanted to uboot bootargs as :console=ttymxc0,115200 init=/init rw video=mxcfb0:dev=ldb,1024x600M@60 video=mxcfb1:dev=lcd,1280x720M@60,if=RGB24,bpp=32 , I failed to get LVDS + VGA dual display.

WE HAVE been successful in dual-display with lvds + VGA on android 4.0.4 , now, we updated to android 4.4.2 , then I
found we can not be successful in the lvds + VGA dual display issue . And we found the dual dispaly setting already was removed , but we used this to achieve our LVDS + VGA dual-dispaly. So how can we deal with this problem on android 4.4.2 ,
this is urgent , I hope you can help us
