Pretty sure most of you already know this but for those who don't: you have two clipboards in Linux. One is the traditional clipboard where you copy with control c and paste with control v. The other one is when you highlight text and use the mouse middle click to paste text.

Well I guess it is configured that way on my EndeavorOS laptop, so I wonder what I need to do to enable it. My desktop has been rolling for 4 years, maybe they added that at some point along the way.
