Make Power Management work on MacBooks and make it configurable #73

Open probonopd opened 3 years ago

probonopd commented 3 years ago

Power Management: Something should happen on closing the lid on a MacBook Pro. At the very least, the screen should be switched off.

https://wiki.freebsd.org/SuspendResume says

For the lid to operate suspend/resume set: sysctl hw.acpi.lid_switch_state=S3

We probably need to make Power Saving opt-in and configurable in a preferences application.

Just set # sysctl hw.acpi.lid_switch_state=S3 if you know that ACPI state S3 (Suspend) works for you.

Could we get the information whether ACPI state S3 (Suspend) works for a particular machine from @linuxhw?

Also see the section on ACPI:

This information may be useful for the upcoming GUI:

Just doing sysctl hw.acpi.lid_switch_state=S3 does not lead to reliable action on MacBook10,3.

Actually it makes it do something, but wakeup is less than ideal.
