Get a 5.12 Linux kernel with support for newer Intel hardware (e.g., Intel Iris Xe for Thinkpad X1 Titanium Yoga) on Ubuntu/Debian/Pop!_OS

Prologue: Do I need this?

I recently got a Thinkpad sporting an Intel® Core™ i5-1140G7 Processor 11. gen (1,80 GHz, Turbo Boost, 4 Cores, 8 Threads, 8 MB Cache with an Integrated Intel® Iris® Xe. Sadly graphics drivers did not work out-of-the-box and also not with the latets 5.12 kernel from xenmod. You can tell it's not working when graphics are slow, backlight adjustment buttons don't work and this is the output of inxi -G (you might need to sudo apt install inxi):

simon@pop-os:~$ inxi -G
Graphics:
  Device-1: Intel driver: N/A 
  Device-2: IMC Networks Integrated Camera type: USB driver: uvcvideo 
  Display: x11 server: X.Org 1.20.9 driver: fbdev unloaded: modesetting,vesa 
 resolution: 2256x1504~95Hz

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).
