Much has been written about resolution scaling in pixel art games. It usually comes down to this simplistic rule: always resize 2D games by integer values (2x, 3x, 4x, 5x, etc) so pixel art will always look correct.
I wrote that myself; to make a good looking low-res pixel art game on modern monitors, you should stick with a 384×216 resolution and scale it up 5 times to get a perfect 1920×1080 (1080p) game.
This article will guide you through the setup of a Xubuntu 16.04 LTS Virtual Machine to test, compile and run your GameMaker Studio 2 projects on Linux.
I’m choosing Xubuntu instead of Ubuntu simply because Xubuntu is less resource hungry (and my notebook is 5 years old I got a new notebook btw). The resulting package will run just fine on Ubuntu machines as well.
