LTS Enablement Stacks
The Ubuntu LTS enablement (also called HWE or Hardware Enablement) stacks provide newer kernel and X support for existing Ubuntu LTS releases. These enablement stacks can be installed manually but are also available when installing with Ubuntu LTS point release media. These newer enablement stacks are meant for desktop and server and even recommended for cloud or virtual images.
Ubuntu 16.04 LTS – Xenial Xerus
The 16.04.2 and newer point releases will ship with an updated kernel and X stack by default for the desktop. Server installations will default to the GA kernel and provide the enablement kernel as optional.
The 16.04 HWE Stacks will follow a new Rolling Update Model as documented at the following location:
It is highly recommended to read the above documentation before executing the following commands, as the HWE model has changed in 16.04.
Installing the HWE stack is simple:
sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04
sudo apt-get install --install-recommends linux-generic-hwe-16.04
