Requires some tweaking when using x11-wm/dwm but should work when using a more advanced window environment like Xfce (at least the volume-up and the volume-down keys)

4. Tweaks

4.1. Disable power button

The power button on the right side of the machine is too easy to hit by accident. It can be disabled with:

sysctl hw.acpi.power_button_state=NONE

It can be done automatically. See man 5 sysctl.conf.

4.2. Headphones

Headphones do not work out of the box. In order to use them it is necessary to add the following to /boot/device.hints:

hint.hdaa.1.nid22.config="as=1 seq=15"

Now they should just work.

4.3. Volume keys

The volume keys are not working out-of-the-box with x11-wm/dwm.

XF86AudioRaiseVolume

In order to bind the volume-up and the volume-down keys it is necessary to include the X11/XF86keysym.h header into dwm's config.h (using XF86XK_AudioRaiseVolume and XF86XK_AudioLowerVolume, respectively)

It is not so straightforward to bind the mute key, however. x11/xev reports that the mute key has no keysym although the keycode value of 140 suggests that it might be SunFront. The solution is to:

  1. Use x11/xmodmap to bind the mute key to XF86AudioMute:
    xmodmap -e "keycode 140 = XF86AudioMute"
  2. Bind XF86XK_AudioMute to an action of your choice in dwm's config.h.
