If you're not an old school [[unix]] user and want to know what it feels like, this is how I fixed my mouse sensitivity -- after probably breaking it somehow in the past :)
@flancian Why use Unix, instead of an operating system that eg handles the mouse sensitivity behind the scenes for you?
@TetraspaceGrouping a recurring question :)
I could have that with GNU/Linux I think, it's just that the magic usually comes with a desktop environment that I don't use.
