Ubuntu 14.04 LTS — Trusty Tahr

Desktop:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial

Server:

sudo apt-get install --install-recommends linux-generic-lts-xenial

The 14.04.2 and newer point releases ship with an updated kernel and X stack by default. If you have installed with older media, you can use these instructions to install the newer HWE kernel derived from 16.04 (Xenial).

If you run a multiarch desktop (for example, i386 and amd64 on amd64, for gaming or Wine), you may find you need a slightly more involved command:

sudo apt-get install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-xenial xserver-xorg-video-all-lts-xenial xserver-xorg-input-all-lts-xenial libwayland-egl1-mesa-lts-xenial libgl1-mesa-glx-lts-xenial libgl1-mesa-glx-lts-xenial:i386 libglapi-mesa-lts-xenial:i386
