Description David Edmundson 2012-09-22 20:11:42 UTC 
Rationale:
<aseigo> beyond that, however, we have a device here used in schools in switzerland and they have settings via powerdevil that does things like map the power button on the tablet to do a sleep (rather than power off)

We need the powermanagement kded module to run.

[20:52] <aseigo> well, it is a kded module, but you don't need to be running kded
[20:52] <aseigo> can just load the plugin directly (either in the greater process or in an external process that only does that)
[20:53] <aseigo> this would let us share the capabilities with the desktop

This can't be done from using Upower directly, and it keeps our code leaner.

Other observations:
We need to work out how to do the config.

Also Lightdm.conf has options to inhibit shutdown/restart etc. I don't want to ignore these, so we should still check these when setting the buttons.

Implemented, didn't seem to do anything.

Needs further investigation

We no longer use lightDM, having moved to SDDM several years ago. As such, this bug report is no longer applicable. Bugs reports for the new SDDM-based login screen should be filed to one of two places:

1. Visual/UI bugs with the login screen UI itself, or feature requests: plasmashell | Theme - Breeze
2. Bugs with the login/user switching process: https://github.com/sddm/sddm/issues
