how to get and install Intel i915 drivers on ubuntu 18.04?

Good day all

please could someone help me as i think I am a bit stuck, I want to install the Intel 915 drivers on my HP Elitebook 2540p (yes i know its an artifact), I am using this laptop as a side project to learn and understand Linux and its interfaces a bit better, so my question to you is how and where do I go / get the drivers to install on Kubuntu 18.04

Ubuntu has Intel video drivers by default in the package xserver-xorg-video-intel. But you can install the newest version from ppa:

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update
sudo apt dist-upgrade
