Startx problem with imx6q /imx6dl with ubuntu

Hi,

We have got IMX6Q/IMX6DL reference board (Wandboard) which is working fine with pre-built images. When we are downloading 3.10.53 or 3.14.14 or any other kernel source and cross-compile it and use ubuntu-core-14.04.2-core-armhf.tar.gz (rootfs).

 

When every thing is deployed like kernel image. rootfs, modules, firmware, dtbs etc to sd card and powering on the target board, boots to ubuntu 14.04, but desktop gui (gnome, kde,lxde) etc are not coming even though they are getting installed successfully. it is always going to terminal...

 

are we lagging in any of the steps to set up Xorg????

 

is there any procedural steps or document to setup xorg in imx6 q boards. i think gpu (vivante) drivers are already loaded in the kernel... so, no need of installing them again...

 

When Iam running startx, it is failing and giving segmentation fault :
