Intel for display, NVIDIA for computing

This guide will show you how to use Intel graphics for rendering display and NVIDIA graphics for CUDA computing on Ubuntu 18.04 / 20.04 desktop.

I made this work on an ordinary gaming PC with two graphics devices, an Intel UHD Graphics 630 plus an NVIDIA GeForce GTX 1080 Ti. Both of them can be shown via lspci | grep VGA.

/* This is a demonstration program to illustrate a straightforward way of
calling the PCRE2 regular expression library from a C program. See the
pcre2sample documentation for a short discussion ("man pcre2sample" if you have
the PCRE2 man pages installed). PCRE2 is a revised API for the library, and is
incompatible with the original PCRE API.

Setup

Install the dependencies for the archiso package:

(root): pacman -S make squashfs-tools libisoburn dosfstools patch lynx devtools git

I recommend archiso getting them from git, there is a package in the repositories, however, at this time of writing, it will not work with the instructions below. So, grab the most recent version from git and install it:

(user): git clone git://projects.archlinux.org/archiso.git && cd archiso
