Description jm.ouwerkerk 2018-03-12 21:33:10 UTC
Latest powerdevil appears to default to doing nothing when closing the laptop lid. In terms of usability this is a somewhat poor default. I do not know whether it is relevant, but I start plasma + kwin using `startplasmacompositor`, i.e. running a Wayland setup.

Steps to reproduce:

 1. Install your plasma system
 2. Login on a tty & run `startplasmacompositor`
 3. Close laptop lid.
 4. Notice nothing happens.
 5. Log off/kill your plasma session
 6. Close laptop lid.
 7. Notice logind takes care of business as expected.
 8. Run another Plasma session (`startplasmacompositor` again) 
 9. Take a closer look at power settings in system settings
 10. Notice "Button events handling" is not checked, notice the greyed out option for configuring laptop lid handling is marked as "do nothing"
 11. Manually configure closing the laptop lid to suspend to RAM.
 12. Apply settings.
 13. Observe things work as expected, again, from within Plasma.

Extra information:

 - I am using systemd/logind

Confirmed here on Kubuntu 18.04beta.
powerdevil 5.12.4.

The importance of this issue should be raised, since users might damage their laptops by carrying them without realizing they're not suspended, as reported here: https://bugs.kde.org/show_bug.cgi?id=349750

It broke with the shortcuts migration, the config file will never be empty and as such it will never generate its default profiles, omg. will fix asap.

Git commit be91abe7fc8cc731b57bec4cf2c004c07b0fd79b by Kai Uwe Broulik.
Committed on 25/04/2018 at 08:57.
Pushed by broulik into branch 'Plasma/5.12'.

Ignore "migration" key for determining whether the config is empty

Otherwise we would never generate the default power management configuration
leading to it not suspending on lid close, not handling power buttons etc etc

CHANGELOG: Fixed bug that caused power management system to not work on a fresh install
