Here's a computer based riddle for all the linux geeks out there:
You just installed Ubuntu 20.04 on your shiny new laptop! The system boots you into your user and shows you the desktop. However, to your dismay, the drivers for your touchpad, USB ports, Bluetooth adapter and WiFi adapter were not installed. How would you shut this computer down?
Note: you may not access any other tools. The battery is not removable, and do you seriously think you can wait for 10 hours for the battery to run out?
Note that there are multiple solutions to this problem; the one that shuts the computer off in the safest way (least data loss) is the correct one. Also note all ACPI drivers are loaded and running well.
