| We learned that multimedia keys are available by using <tt>xev</tt>. To use it, start <tt>xev | grep keycode</tt> and press the buttons in question. | | We learned that multimedia keys are available by using ''showkey''. To use it, one has to go to a text terminal, start ''showkey'' and press the buttons in question. |

|
| Notice: ''if your window manager evaluates the pressed keycodes, nothing will show up.''
| | The shown keycodes should be placed in <tt>~/.Xmodmap</tt> |
| | | <source lang="bash"> |
| The shown keycodes should be placed in <tt>~/.Xmodmap</tt> and loaded on X startup by <tt>xmodmap ~/.Xmodmap</tt>. | | keycode 234 = XF86Back |
| | | keycode 233 = XF86Forwardpre |
| Example (ThinkPad X61):
| | keycode 144 = XF86AudioPrev |
| <source lang="lua"> | | keycode 164 = XF86AudioStop |
| keycode 113 = XF86AudioMute | | keycode 162 = XF86AudioPlay |
| keycode 114 = XF86AudioLowerVolume | | keycode 153 = XF86AudioNext |
| keycode 115 = XF86AudioRaiseVolume | | keycode 160 = XF86AudioMute |
| keycode 148 = XF86Launch1 # ThinkVantage Button | | keycode 174 = XF86AudioLowerVolume |
| keycode 163 = XF86AudioNext | | keycode 176 = XF86AudioRaiseVolume |
| keycode 164 = XF86AudioPlay | |
| keycode 165 = XF86AudioPrev | |
| keycode 166 = XF86AudioStop | |

|
| |
| The terminal based program ''showkeys'' won’t work, since kernel keycodes differ from X11.

| These keysyms can be used for your favorite window manager‘s configuration.
| |
|
| |
| Example (awesome):
| |
| <source lang="lua">
| |
| -- Multimedia Keys
| |
| awful.key({ }, "XF86AudioRaiseVolume", function () awful.util.spawn('mpc -h localhost volume +1') end),
| |
| awful.key({ }, "XF86AudioLowerVolume", function () awful.util.spawn('mpc -h localhost volume -1') end),
| |
| awful.key({ }, "XF86AudioMute", function () awful.util.spawn('mpc -h localhost volume 0') end),
| |
| awful.key({ }, "XF86AudioNext", function () awful.util.spawn('mpc -h localhost next') end),
| |
| awful.key({ }, "XF86AudioPrev", function () awful.util.spawn('mpc -h localhost prev') end),
| |
| awful.key({ }, "XF86AudioPlay", function () awful.util.spawn('mpc -h localhost toggle') end)

| == PulseAudio ==
| |
|
| |
| PulseAudio is a sound system enabling us to control application volumes individually and use other computers soundcards over the network.
| |
|
| |
| Recommended packages:
| |
| * pulseaudio (the daemon, required)
| |
| * pavucontrol (GTK based mixer application)
| |
| * paprefs (GTK based configuration tool)
| |
| * pulseaudio-alsa
| |
|
| |
| With ''pulseaudio-alsa'', applications may use a virtual ALSA device for output. They show up as regular PulseAudio clients and there is an ALSA mixer channel to control the volume.
| |
|
| |
| Note: in order to discover remote soundcards, one has to start ''avahi-daemon''!
