xorg failing after changing the kernel

Hi,

We have got IMX6Q /IMX6DL reference boards. We have tried Ubuntu 3.10.53 and it is working fine. We have run some applications with qt, openCV etc.

Now When we have replaced kernel (vmlinuz-3.10.53) with another kernel (vmlinuz-3.14.14), then display/Desktop GUI (Kde-plasma-desktop) is not coming and it is going to terminal. I can able to login from terminal using user name and password.

All the files are there ( for ex: if i do $ cd ~/Desktop and then ls, it is listing out all the files)

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