Fix unity kernel-level issues

To update the Kernel to 2.6.39-0, 0pen the Terminal and add the PPA (Personal Package Archive) by entering the below mentioned commands:

sudo add-apt-repository ppa:kernel-ppa/ppa

sudo apt-get update

After that, check available Kernal by entering the below command. Version 2.6.39.0 kernel should appear in the list.

apt-cache showpkg linux-headers

Then, run this command to update your Kernel.

sudo apt-get install linux-headers-2.6.39-0 linux-headers-2.6.39-0-generic linux-image-2.6.39-0-generic --fix-missing

Restart your system to complete the update. The system might become slow for a while, that’s normal since the Kernel will be updating during this time.
