# Power button starts a system shutdown.
# Sleep button suspends the machine to ram.
#   - delegated this to my WM (Fn+F6 to disk, Fn+F1 to ram)
# AC events start laptop_mode (which also controls cpufreq or throttling).
# Battery events auto-hibernate on low battery through laptop_mode.
# Lid handler locks the screen when someone tries to open it.
