Backlight Control

inside /etc/default/grub

append GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi='!Windows 2012'"

then regenerate the config file with grub-mkconfig -o /boot/grub/grub.cfg

Hibernation

inside /etc/default/grub

append GRUB_CMDLINE_LINUX="resume=/dev/sdXX" (sdXX = SWAP)

then regenerate the config file with grub-mkconfig -o /boot/grub/grub.cfg

edit how systemd handles sleep and hibernation with sudo $EDITOR /etc/systemd/logind.conf

append

HandleLidSwitch=suspend
HandleLidSwitchDocked=ignore
HandleLidSwitchExternalPower=HandleLidSwitch

to apply any changes signal systemd-logind with HUP systemctl kill -s HUP systemd-logind

to hibernate on low battery level make sure to have acpi installed and append

# Suspend the system when battery level drops to 8% or lower
SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", ATTR{capacity}=="[0-8]", RUN+="/usr/bin/systemctl hibernate"

to /etc/udev/rules.d/99-lowbat.rules

testing events: one way to test udev rules is to have them create a file when they are run.

to /etc/udev/rules.d/98-discharging.rules

apppend SUBSYSTEM=="power_supply", ATTR{status}=="Discharging", RUN+="/usr/bin/touch /home/example/discharging"

This creates a file at /home/example/discharging when the laptop charger is unplugged

Hybrid-sleep on suspend or hibernation request

It is possible to configure systemd to always do a hybrid-sleep even on a suspend or hibernation request.

The default suspend and hibernation action can be configured in the /etc/systemd/sleep.conf file. To set both actions to hybrid-sleep, append

[Sleep]
# suspend=hybrid-sleep
SuspendMode=suspend
SuspendState=disk
# hibernate=hybrid-sleep
HibernateMode=suspend
HibernateState=disk

to /etc/systemd/sleep.conf

        Option "VelocityScale" "20"
        Option "AccelerationNumerator" "30"
        Option "AccelerationDenominator" "10"
        Option "AccelerationThreshold" "10"
	# Disable two fingers right mouse click
	Option "TapButton2" "0"
        Option "HorizHysteresis" "100"
        Option "VertHysteresis" "100"
        # fix touchpad scroll speed

        Option "HorizScrollDelta" "500"
EndSection

Power Saving

TLP

install tlp with sudo pacman -S tlp

enable startup systemctl enable tlp.service

run tlp systemctl start tlp.service

in /etc/default/tlp add the following:

START_CHARGE_THRESH_BAT0=67
STOP_CHARGE_THRESH_BAT0=100

Charge thresholds

# echo 40 > /sys/class/power_supply/BAT0/charge_start_threshold
# echo 80 > /sys/class/power_supply/BAT0/charge_stop_threshold

Note: after battery removal, default value will be loaded.

Fan control

install AUR thinkfan and configure /etc/thinkfan.conf with:

tp_fan /proc/acpi/ibm/fan
hwmon /sys/class/thermal/thermal_zone0/temp

(0, 0,  60)
(1, 53, 65)
(2, 55, 66)
(3, 57, 68)
(4, 61, 70)
(5, 64, 71)
(7, 68, 32767)

Kernel

in /etc/mkinitcpio.conf, add MODULES="i915". Regenerate initram image with sudo mkinitcpio -p linux.
