===== Tweaks =====

==== 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:

<code>
sysctl hw.acpi.power_button_state=NONE
</code>

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

==== 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%%'':

<code>
hint.hdaa.1.nid22.config="as=1 seq=15"
</code>

Now they should //just work//.

=== Resources ===

  * [[https://unix.stackexchange.com/a/185021/128489|FreeBSD 10.1 sound not working (unix.stackexchange.com)]]
  * ''%%man 4 snd_hda%%''

==== Volume keys ====

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

| **Physical key** | **//keycode//** | **//keysym//** |
| F1 | 140 | //no symbol// |
| F2 | 174 | ''%%XF86AudioLowerVolume%%'' |
| F3 | 176 | ''%%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:

  - Use x11/xmodmap to bind the mute key to XF86AudioMute:

<code>
xmodmap -e "keycode 140 = XF86AudioMute"
</code>

  - Bind ''%%XF86XK_AudioMute%%'' to an action of your choice in dwm's ''%%config.h%%''.
