In order to make my raise/lower/mute sound buttons work, I added
awful.key({ }, "XF86AudioRaiseVolume", function ()
awful.util.spawn("amixer set Master 9%+") end),
awful.key({ }, "XF86AudioLowerVolume", function ()
awful.util.spawn("amixer set Master 9%-") end),
awful.key({ }, "XF86AudioMute", function ()
awful.util.spawn("amixer sset Master toggle") end)
to rc.lua.
Buttons work perfectly now, i.e. they change the volume. However whenever I
press one of those buttons, my mouse pointer turns into a watch for about
20 seconds. Is this a feature, or could I fix it somehow?
