"""
A simple sketch to make sure spherical projection and unprojections work
properly. There are many ways to encode them, so this one assumes
THETA as rotating around Y (horizontal plane positionning) and PHI as the
rotation around Z (vertical positioning), so that THETA can be considered
the spherical X and PHI the spherical Y.

This is a step-by-step guide on how make sleep mode work with a Lenovo Yoga X1 3rd generation running Fedora 28 (UEFI based system).
Kernel version: 4.17.4-200.fc28.x86_64

Credits: most of this guide comes from `https://delta-xi.net/#056`. The patch I used is a little different though, taken from http://kernel.dk/acpi.patch 
(found through https://bbs.archlinux.org/viewtopic.php?pid=1794150#p1794150), and some of the steps slightly differ as well as mine is a UEFI based system.

1. Reboot, enter BIOS/UEFI. Go to Config - Thunderbolt (TM) 3 - set Thunderbolt BIOS Assist Mode to Enabled. Set also Security - Secure Boot to Disabled.

2. Install iasl (Intel's compiler/decompiler for ACPI machine language) and cpio: `sudo yum install acpica-tools cpio`
