Wandboard quad, LVDS+HDMI

[Yaroslav Polekhov]

Hi everyone.
I'm using wandboard quad with ubuntu SD-card image from wandboard web-site (linaro 12.04 LTS).
I want to connect LCD - NEC NL10276BC13-01 1024x768@60 - through LVDS port. I've done all the hardware work and when I start the board it draws linux penguins on the screen. But I can't see this LCD through display settings in UI (System Settings -> Displays). I change u-boot parameters to this:
bootargs=console=ttymxc0,115200 root=/dev/mmcblk0p1 rootwait rw  video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24
video=mxcfb1:dev=ldb,1024x768M@60,if=RBG=666 fbmem=28M,10M.
If I change mxcfb0 to LVDS it works fine as main monitor, but no detection of HDMI-monitor.

Following this instructions https://community.freescale.com/docs/DOC-93449 I was able to play video on LCD while HDMI is main monitor, but I want to use it as a separate monitor or at least mirror of desktop.
According to this note https://groups.google.com/forum/embed/?place=forum%2Fwandboard&showsearch=true&showtabs=false&parenturl=http%3A%2F%2Fwww.wandboard.org%2Findex.php%2Fforums&theme=default#!topic/wandboard/c-pwS4R0knw I checked board-wand.c in searh of ldb configuration, and it was already in it.

Any advice?
Best regards

Just a guess, but you probably need to unblank the second framebuffer.  Try:  echo 0 > /sys/class/graphics/fb2/blank

Thanks for the answer, but that didn't help
