Public bug reported:
Some applications prevent the computer from going to suspend mode (applications
that display video, eg. chromium, opera, openshot) because they assume it is in
the user's interest to keep the screen on even when inactive. This is most
times helpful and saves the user from having to move a finger. But on low
battery power, the user's inactivity could also be due to absence or sleep, and
keeping the computer on until the power is 0.000% causes more damage than it
serves the user's interest:
- battery drain over time
- data loss
We can not rely on that every application implements sophisticated power
management in the user's interest and has no malicious intentions. It is
crucial that the operating system still reserves to have the last word
in resource and power management.
Steps to reproduce:
1. Watch a video in Opera (36) in full screen
2. Fall asleep
3. After some hours, the computer is either still on (with battery <3%) or
already off
Expected behavior:
When not connected to an external power source and battery has low power
(<30%), the usual procedure for suspend is still applied:
1. Notification on inactivity
2. Suspend
There may be a way to configure this manually, but I think due to the
implications of hardware drain and data loss Ubuntu should come with a
reasonable default that serves the interests of general, unconscious
users.
