Ubuntu 16.04 LTS kernel lifecycle and enablement stack

The Ubuntu LTS enablement, or Hardware Enablement (HWE), stacks provide the newer kernel and X.Org support for existing Ubuntu LTS releases. These stacks can be installed manually, but are also installed with an Ubuntu LTS point release.

The 16.04.2 and newer point releases ship with an updated kernel and X.Org stack by default for the desktop. Server installations default to the General Availability (GA) kernel and provide the enablement kernel as optional.

Ubuntu 16.04 ESM includes support for v4.4 and v4.15 based generic, lowlatency, hwe-16.04, aws and azure Linux kernel flavours.

Installing the Ubuntu 16.04 LTS HWE stack:

Desktop:
sudo apt-get install --install-recommends linux-generic-
          hwe-16.04 xserver-xorg-hwe-16.04
Server:
sudo apt-get install --install-recommends linux-generic-
            hwe-16.04
