You generally don’t need to install hardware drivers on Linux. It’ll automatically detect the hardware in your computer and set it up for you — that’s the goal. But printers can be a different story.
Linux is often best installed in a dual-boot system. This allows you to run Linux on your actual hardware, but you can always reboot into Windows if you need to run Windows software or play PC games.
Wireless devices with Bluetooth radios must be “paired” with each other before they can communicate. This involves making them discoverable and potentially entering a PIN.

Ubuntu’s installer offers an easy “Use LVM” checkbox. The description says it enables Logical Volume Management so you can take snapshots and more easily resize your hard disk partitions — here’s how to do that.
Ctrl+Alt+Delete isn’t just necessary on Windows and other desktop operating systems. Applications can freeze or get stuck in bad states on modern iPhones, iPads, and Android devices too.
