As teclas de mídia não funcionam

Question

As teclas de volume sem áudio, volume baixo e volume estão funcionando, mas minhas teclas anterior, seguinte e reproduzir / pausar não estão.

Eu tentei a solução postada aqui , mas esse não parece ser o problema. Todas as minhas configurações de org.gnome.settings-daemon.plugins.media-keys parecem ser apropriadamente prefixadas pelo XF86:

Eudecidiinvestigarissoumpoucomais.Aparentemente,sevocêtemumtecladoUSB, você precisa usar evtest em vez de showkey para obtenha os scancodes adequados:

Consegui verificar se minhas chaves estavam funcionando remapeando-as para as letras :

$ cat /etc/udev/hwdb.d/90-custom-keyboard.hwdb 
evdev:input:b0003v1130p7979*
 KEYBOARD_KEY_c00cd=a
 KEYBOARD_KEY_c00b6=b
 KEYBOARD_KEY_c00b5=c
$ sudo udevadm --debug hwdb --update
$ sudo udevadm trigger

Agora posso escrever letras com as minhas teclas anterior, seguinte e reproduzir / pausar. Em seguida, usei xdotool para testar as chaves:

$ xdotool key XF86AudioLowerVolume
$ xdotool key XF86AudioRaiseVolume

ambos funcionam, mas nenhum dos seguintes faz alguma coisa

$ xdotool key XF86AudioPlay
$ xdotool key XF86AudioNext
$ xdotool key XF86AudioPrev

Isso me faz pensar que o Unity está perdendo a bola com sua integração com o media player, de alguma forma. Não sei como verificar se a Unity está fazendo a coisa certa nos bastidores. Alguma idéia?

Answer 1

As teclas de mídia do funcionam (com o rhythmbox). Eles não funcionam com banshee ou VLC porque há um bug com banshee 2.6.2 e VLC 2.2.2 no Ubuntu 16.04.

Uma solução para o VLC é definir uma tecla de atalho global .

    

Answer 2

Como @Jeffrey afirma em sua resposta , as teclas de mídia funcionam com o rythmbox v.3.3. Eles também trabalham no totem v.3.18.1 sem nenhum ajuste necessário.

Também conhecido por trabalhar com o teclado multimídia sem fio Rosewill RKM-1600RF (RF6560) de 2,4 GHz
