Keyboard

The keyboard has the following special keys:

  • F1 triggers the display settings
  • F2 does nothing
  • F3 decreases the display brightness
  • F4 increases the display brightness
  • F5 mutes/unmutes the volume.
Tip
In order to make the mute LED working, make sure to install the required kernel modules along with ALSA/PulseAudio, and to add the following to /etc/modprobe.d/alsa.conf
FILE /etc/modprobe.d/alsa.conf
...
options snd-hda-intel model=mute-led-gpio

This also allows the microphone mute LED (on F8) to work whenever you mute/unmute the microphone. If the mute LED is still not working, run alsamixer and make sure that Mute-LED mode is set to Follow Master.

  • F6 decreases the volume
  • F7 increases the volume
  • F8 mutes/unmutes the microphone
  • F9 toggles the keyboard backlight and its intensity
  • F10 does nothing
  • F11 toggles Wi-Fi status
Note
You need to build CONFIG_IWLWIFI and CONFIG_HP_WIRELESS as kernel modules (or built-in) in order for the button to correctly work. As of now, the wireless LED stays on regardless of its state, I will update the section if I will manage to make this work.
  • F12 can be bound to open the calendar

To access F1-F12 you need to keep pressed the fn key.

Tip
Hold fn and Shift to block the function keys. The LED on the fn key should light up.

Smart card reader

In order for the smart card reader to work, install dev-libs/opensc and app-crypt/ccid.

root #emerge --ask dev-libs/opensc app-crypt/ccid

Reboot and if you insert a smart card in the smart card reader it should be detected and a notification should appear.
