You'll find, as I have, that laptops and Linux distributions/DEs don't always play well together (lid closing/reopening, suspend/hibernate, keyboard backlight, function key alternate media controls, trackpad, etc). It's sometimes a shot in the dark if not buying from a company that helps guarantee Linux support/compatibility for all the hardware in the system (Dell XPS 13 plus developer, System 76, etc).
That's great there was a tutorial that got everything working well, especially for your specific setup! I'm also now running Linux as my only operating system on my gaming desktop machine (I run Arch, btw ;D ). Steam/Proton and Lutris make gaming a relative cinch now, and I've been hoping for this since I first started with Linux in 1999.
