@Thargor: It's a tiny bit more complex than "at the bottom of the config file".
It has to be inside the "PowerOptions" section.
Purely for example, that section of my own config file currently looks like this:
Code:
[PowerOptions]
AutoColorEnabled=false
BedTime=@Variant(\0\0\0\xf\0m\xdd\0)
ColorSetting=2970
FrontLightLevel=12
FullscreenCoverInfoPanel=false
FullscreenCoverStretch=true
IndicatorCharging=true
SleepAccessoryEnabled=false
UnlockEnabled=false
(While here, the bottom of the file would be the "Services" section).
You'll then have restart the device to pickup the change.
