Ubuntu 19.10 Power Management

I recently installed the latest Ubuntu Linux on my laptop and found the default power management settings to be way too aggressive. While operating on battery power, the laptop would essentially boot Linux and then immediately enter suspend mode.

This solved the problem entirely:

$ sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target

Thank you, Dustin Kirkland.
