Create the file /etc/X11/xorg.conf.d/50-touchpad.conf and add the following to it:
Section "InputClass"
Identifier "touchpad"
MatchIsTouchpad "on"
Option "FingerHigh" "5"
Option "FingerLow" "5"
EndSection
- Install alsa-utils:
pacman -S alsa-utils
- Run alsamixer as root.
- Arrow right until you see four items starting with Left Speaker Mixer, and press M on all four channels to un-mute them.
- Arrow right some more until you find four more starting with Right Speaker Mixer and un-mute them as well.
- Arrow all the way back left to the Speaker channel and raise the volume a little. Keep it low (< 50ish), since alsa will let you get dangerously high for these speakers.
Install acpid and pm-utils: pacman -S acpid pm-utils
Edit /etc/acpi/handler.sh and near the bottom you'll see the button/lid section. Add pm-suspend to the close section to look like:
button/lid)
case "$3" in
close)
logger 'LID closed'
pm-suspend
;;
Enable and start acpid:
systemctl enable acpid
systemctl start acpid
Closing the lid will now trigger a suspend, and opening it will wake the system.
To allow all users to modify the backlight control at /sys/class/backlight/pwm-backlight.0/brightness, create and edit the file /etc/tmpfiles.d/brightness.conf with these contents:
f /sys/class/backlight/pwm-backlight.0/brightness 0666 - - - 800
On boot, systemd will now set the permissions of that control file to be world writable. Acceptable values are 0-2800.
