The Pandaboard list seems dormant so I am seeking help here.
The previous kernel with HDMI video output was 3.2.7x5.
I built and installed this new kernel with this xorg.conf, it does not
work.

Using the udlfb driver and an xorg.conf for the Lilliput USB 7" screen
there is no problem, LXDE is up and running and CRTL-ALT-F1 etc. all
OK, but I need the USB screen for the Beaglebone.

Hi,
There are a couple of options here.

Looks like the problem below was buffer allocation. You could use
omapdrm instead of omapfb which should allocate buffers successfully. I
think the omapdrm drivers was in staging at that point. You could search
for it in the .config, and set NUM_CRTCS to 2.

The other option is to figure out why it's not working with omapfb.
Could you add a CONFIG_OMAP2_DSS_DEBUG in order to get additional DSS
prints?

The debug prints will help with the edid timeout. About the allocation
of buffers, I think it should work if you enable CMA. And set
CONFIG_CMA_SIZE_MBYTES to say, 24 Mb. That should allocate the buffers
successfully.
