Other tweaks

No explanations with these tweaks? What do these do? Is linking to the source enough or should we describe what we're doing in detail? I'm never too comfortable with "do this" type instructions without a "this is why" explanations.--Multiphrenic 09:05, 27 April 2011 (EDT)

Udev Rule to Suspend System

The udev rule could be edited to run a script that does polls the battery's capacity at regular interval when it's status changes to Discharging:

SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="2", RUN+="/usr/bin/systemctl suspend RUN+="/script/to/poll/battery/and/suspend/"

There may also be a uevent that fires when the battery reaches an alarm state (when /sys/class/power_supply/BAT*/alarm is reached or changes). I have not tested this on my own system yet or figured out just how that file works yet. Ego.abyssi (talk) 23:32, 3 March 2013 (UTC) Strange, on my system battery sends "change" uevent each time battery is charged or discharged by 1%, so rule works perfectly and polling is an overcomplication. --Eruditorum (talk) 06:48, 30 March 2013 (UTC)
