From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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.

I don't believe anything is actually copied until you request it to be pasted. The clipboards in Linux mark where the data is, and don't actually initiate a copy until there's a destination.

Yes. You can test this by selecting something, closing that window and attempting to paste. It won't work. Closing the window removes the information about what was highlighted, so there is nothing to paste. If it were to copy upon selection you'd still be able to paste.
