Intro:
Linux is open source, anyone can grab the code and distribute their own Linux distro, some of them are community Maintained, some are backed by big companies. Some of them are based on another distro and they change stuff, a spin off of sorts. Think of Linux as a big waterfall which then is forked into several rivers, and then forked into more rivers. Each river has it's own characteristics, which some come from upstream and some others are their own.
There are four big players: Debian, Ubuntu (which is based on Debian), Fedora and Arch. Then you have POP OS and Linux Mint which are based on Ubuntu, but they change stuff to make it even easier to use, specially for Nvidia users.
In Linux, everything works out of the box because every driver is part of the core of Linux called the Linux Kernel. Except for Nvidia, for which you need their own non-open source, proprietary driver. Installing that driver manually is much harder than on Windows, so that's why everyone recommends a distro that ships with Nvidia drivers out of the box.
I don't know how they will behave with double touchscreens. Try some distros and report back please.
OS
All major Linux distros have no ads For a PC with Nvidia GPU, pick a distro that ships with Nvidia drivers. Like POP OS & Linux Mint.
