Requires `pulseaudio pavucontrol alsa-lib alsa-utils acpilight`
|
|
|
|
Actual requirements may vary depending on your configuration. I am only writing what worked for me.
|
|
<!--more-->
|
|
|
|
Edit `config.h`
|
|
|
|
```c
|
|
#include <X11/XF86keysym.h>
|
|
|
|
/* volume keys*/
|
|
static const char *upvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "+5%", NULL };
|
|
static const char *downvol[] = { "/usr/bin/pactl", "set-sink-volume", "0", "-5%", NULL };
|
|
static const char *mutevol[] = { "/usr/bin/pactl", "set-sink-mute", "0", "toggle", NULL };
|
|
|
|
/* backlight */
|
|
static const char *brightnessup[] = { "sudo", "xbacklight", "-inc"m "5", NULL };
|
|
static const char *brightnessdown[] = { "sudo", "xbacklight", "-dec", "5", NULL };
|
|
```
|
|
|
|
Append the following lines in `static Key keys[]` array
|
|
```c
|
|
static Key keys[] = {
|
|
{ 0, XF86XK_AudioLowerVolume, spawn, {.v = downvol} },
|
|
{ 0, XF86XK_AudioMute, spawn, {.v = mutevol }},
|
|
{ 0, XF86XK_AudioRaiseVolume, spawn, {.v = upvol} },
|
|
{ 0, XF86XK_MonBrightnessUp, spawn, {.v = brightnessup} },
|
|
{ 0, XF86XK_MonBrightnessDown, spawn, {.v = brightnessdown} },
|
|
};
|
|
```
