Hi every body,

  i know that che argument is everywhere is the forum , but i'm not able to do it. I really devasteted. I need to have a dual display, LVDS and HDMI with the same thing displayed.

I have a iMX& with kernel 3.0.35 and ubuntu 11.01

 

I configure uboot as:

 

video=mxcfb0:dev=ldb, LDB-VGA,if=RGB666 video=mxcfb1:dev=hdmi,1920x1080M@60,if=RGB24

 

the first diplay (lvds) works perfectly, but the second (hdmi) don't.

I cheched on /sys/class/graphis and on fb2 i have the hdmi. i cheched name file and modes. If i send a echo 1 > /sys/class/graphics/fb2/blank doesn't do anything on the hdmi display connected. If i do the same on fb0 (lbvds), it immediatelly switch off.

 

Can someone help me please?

 

 

Thanks
