## Better touchpad responsiveness
|
|
|
|
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
|
|
```
|
|
|
|
## Enable audio
|
|
|
|
1. Install alsa-utils: `pacman -S alsa-utils`
|
|
2. Run alsamixer as root.
|
|
3. Arrow right until you see four items starting with Left Speaker Mixer, and press M on all four channels to un-mute them.
|
|
4. Arrow right some more until you find four more starting with Right Speaker Mixer and un-mute them as well.
|
|
5. 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.
|
|
|
|
## Suspend when closing the lid
|
|
|
|
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.
|
|
|
|
## User permissions for backlight control
|
|
|
|
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. |
