sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopicThe open source driver radeon is working perfectly on Kernel 3.16
This Laptop has Realtek Wireless Network Adapter and its driver rtl8723be was causing disconnections and required reboot to connect again. This is solved by following command:

Now Ubuntu 14.04 is working perfectly on this Laptop.
