Install ukuu: (Gets mainline linux kernels for ubuntu)
-----------------------------------------------------
sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update && sudo apt-get install ukuu

*Note for updating to mainline Linux Kernels: There are less stable then the ones included with ubuntu default and especially ubuntu lts default and is best to keep the default linux ones installed in case of system failure.
