I think I found a bug

stop bme
modprobe bq2415x_charger

->Display turns off while charging: I wanted to leave it on because sometimes it cannot be unlocked, so I have to remove the battery.


//Edit: Okey with simple brightness widget the display can run 24/7
I noticed that SSH works even if the display is off and not unlockable. Maybe this can be used to get debug information.
