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.

Laptops usually have a dedicated key to turn off the screen, no?
You mean the external display toggle? Because otherwise, no.
Mine doesn't, but even if it would have, most of the original special keys don't work in Linux. It's quite annoying because I don't have F keys and Home-PageUp and such, they were accessible with key combinations with the original OS.
On most laptops that do that, there's a BIOS setting that fixes it, the F keys at least. On HP's, you can set whether you want the top row to act as F keys or "media" keys. Any combo that uses the Fn key should work in Linux, and you can set your own hot-keys/shortcuts in Linux as well.
