[SOLVED] Setup of function keys on ThinkPad A485 in i3wm

Hi,

i have installed Arch on the Lenovo ThinkPad A485 with i3wm as window manager. So far I managed to make the basic stuff work except none of the function keys work. I know this is a configuration problem, since I they worked fine in a quick-and-dirty Antergos installation I previously had on the laptop for fast testing of hardware support.

Here's what I installed:

$pacman -Qe
autoconf 2.69-4
automake 1.15.1-1
bash 4.4.023-1

Here's the output of dmesg concerning the thinkpad_acpi which I guess is handling the function keys:

$ dmesg | grep thinkpad_acpi

Using 

xev

I could verify that the function keys are all mapped to the appropriate XF86 commands:

    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

So the problem is more specifically, that these XF86 keybinds to not trigger the appropriate response with the single exception of XF86WLAN which actually turns WLAN on and off, as it should.

How can I proceed from here?

Best regards

Re: [SOLVED] Setup of function keys on ThinkPad A485 in i3wm

What have you configured to react to these buttons? As evident they are registered, but unless you configured a hotkey or some daemon that specifically listens to them, naturally they will not do anything. Read https://wiki.archlinux.org/index.php/I3#Keybindings an the relevant redirection links for further information.

Re: [SOLVED] Setup of function keys on ThinkPad A485 in i3wm

Up to now I only managed to make the first three function keys for mute and volume up/down work via pulsaudio (not the LED on the mute button however):

bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume 0 +5%
bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume 0 -5%
bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute 0 toggle

For the backlight, setting it via ACPI seems to work well with a script like

#!/bin/bash

BRIGHTNESS=`cat /sys/class/backlight/amdgpu_bl0/actual_brightness`
MAX_BRIGHT=`cat /sys/class/backlight/amdgpu_bl0/max_brightness`

case "$1" in
  up)
    BRIGHTNESS=$((BRIGHTNESS + 32))
    if [ $BRIGHTNESS -gt $MAX_BRIGHT ] ; then BRIGHTNESS=$MAX_BRIGHT ; fi
    echo $BRIGHTNESS > /sys/class/backlight/amdgpu_bl0/brightness
  ;;

  down)
    BRIGHTNESS=$((BRIGHTNESS - 32))
    if [ $BRIGHTNESS -lt 0 ] ; then BRIGHTNESS=0 ; fi
    echo $BRIGHTNESS > /sys/class/backlight/amdgpu_bl0/brightness
  ;;
esac

No idea however what to map the bluetooth button to, which I need so desperatly for my mouse.

Edit: I have opened a thread specifically about turning the bluetooth module on, since this issue seems seperated from merely finding appropriate mappings for the function keys. I'll mark this as solved.

For future reference here the i3 configuration options

# Pulse Audio controls
bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume 0 +5%
bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume 0 -5%
bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute 0 toggle
bindsym XF86AudioMicMute exec --no-startup-id pactl set-source-mute 1 toggle

# Backlight controls via ACPI
bindsym XF86MonBrightnessDown exec ~/.config/i3/scripts/acpi_brightness.sh down
bindsym XF86MonBrightnessUp exec ~/.config/i3/scripts/acpi_brightness.sh up
$ cat .config/i3/scripts/acpi_brightness.sh 
#!/bin/bash

BRIGHTNESS=`cat /sys/class/backlight/amdgpu_bl0/actual_brightness`
MAX_BRIGHT=`cat /sys/class/backlight/amdgpu_bl0/max_brightness`

case "$1" in
  up)
    BRIGHTNESS=$((BRIGHTNESS + 32))
    if [ $BRIGHTNESS -gt $MAX_BRIGHT ] ; then BRIGHTNESS=$MAX_BRIGHT ; fi
    echo $BRIGHTNESS > /sys/class/backlight/amdgpu_bl0/brightness
  ;;

  down)
    BRIGHTNESS=$((BRIGHTNESS - 32))
    if [ $BRIGHTNESS -lt 0 ] ; then BRIGHTNESS=0 ; fi
    echo $BRIGHTNESS > /sys/class/backlight/amdgpu_bl0/brightness
  ;;
esac
$ cat /etc/udev/rules.d/backlight.rules 
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/amdgpu_bl0/actual_brightness"

ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/amdgpu_bl0/max_brightness"
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chmod g+r /sys/class/backlight/amdgpu_bl0/max_brightness"

ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/amdgpu_bl0/brightness"
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chmod g+w /sys/class/backlight/amdgpu_bl0/brightness"

Add the user to the video group to enable him using the blacklight hotkeys.

No, the bluetooth module is not even listed with rfkill list.
