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:
sysctl hw.acpi.power_button_state=NONE
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:
hint.hdaa.1.nid22.config="as=1 seq=15"
Now they should just work.

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:
xmodmap -e "keycode 140 = XF86AudioMute"
- Bind
XF86XK_AudioMuteto an action of your choice in dwm'sconfig.h.
