[issue] display issue on Panda

hello Group,

I am trying to boot the Linaro-Ubuntu-13.04 release on Panda, But the _HDMI_ display is not coming.

- I see the x-server is not started (X doesn't exit, is the window manager changed?). I installed it and started X. But it says error message as "no screen found"

- In Xorg.logs i see message, failed to load omap display module.

Any pointers how to get the display? got a dependency on it.

thanks, sanjay
