As I was looking on the Suburban Railway I noticed that was using Linux:

That made me think can I draw graphics or display anythink in Linux without the use of any sort of display manager/window manager such as wayland or XOrg.

And I found out that yes I can. After a bit of googling I found out that upon linux there are files named as /dev/fb0,/dev/fb1... each file is a mapping to the ram that contains what should be displayed upon the screen.

Via providing the command:

ls -l /dev/fb*
