I’m using Linux Mint, Cinnamon, and I think it’s Debian at it’s core????

Hmm--Not sure now.

I know Mint is Debian-based. I received my Raspberry Pi yesterday, and have been configuring it today. It, too, is Debian-based. However, /var/log/messages does exist on Raspbian.

Are you sure you are in the /var/log directory? Try this:

grep -i mouse /var/log/messages

rather than changing to the right directory, this will point the grep to the right file no matter where you are. Don't forget the slashes.
