I occasionally install and mess around with different flavors of Linux. Linux Mint is a very interesting one, but something that made it darn near impossible to use was the crazy high scrolling rate when using a mouse wheel.
This link has a solution. One thing to note – after you download the .sh file, make sure to either use CHMOD to make it executable, or just use the file browser, go to properties, and check the allow to run as an executable flag.
I ended up using 4 as the scroll speed and it is pretty usable now.
