The shutdown on critical battery level does not finish because of a confirmation window asking for permission to abort active sessions :( I put that one to critical because it made the battery drop to 0 and the abrupt end caused in deed data loss as the filesystem did not like the poweroff. Reproducible: Always Steps to Reproduce: 1. systemsettings - Power Management - Advanced Settings : When battery has reached critical : Shutdown. 2. Critical level: 5% ... or for testing purposes I then set it at "actucal level - 1%" 3. Wait Actual Results: The critical level gets detected. There is a pop-up in the systray, then 30 seconds later logs you out and then there is this beautiful window: Turn off Computer Abort active Sessions: me TTY login ... OK Cancel and it SITS there ... ... and sits there... ... until the battery says: ENOUGH! ;) Expected Results: Forced Shutdown, not caring about sessions. Any way to force the shutdown ?
Ugly workaround: call poweroff in a script, and the window won't appear
But this really is an ugly workaround, because one seems to only be able to execute a custom script on LOW battery and not on CRITICAL battery level. By setting the low battery level to 5% one looses basically the ability of having a pre-emptive low power level (e.g. at 20% battery remaining) that warns and activates some more power saving settings.
