[Solved] Volume down keyboard shortcut works but not volume up

jiewmeng · 2012-05-04 01:37:05

I am using a Microsoft Multimedia keyboard with those "multimedia keys" eg. volume up down etc. I am using XFCE 4.10 and bound those keys to

- /usr/bin/amixer set Master 5%+
- /usr/bin/amixer set Master 5%-
- /usr/bin/amixer set Master toggle

But I notice that volume up does not work ... When I set the shortcut using Settings > Keyboard > Application shortcuts, the button is detected as XF86AudioRaiseVolume, but apart from that, it appears the key does not work? Pressing it does not affect the volume. If I set it to another key eg. Super+Up, it works, so I think its a key problem?

Have you tried xev to check the output of the key?

Ok, I pressed VolUp a few times and the the output:

Check through Xmodmap if the keycode for your volume key is actually bound to an action (XF86AudioRaiseVolume in this case).

You should try it on another OS. A "live" distro could work.

@Gcool, I'm not sure I am using xmodmap correctly but I did

xmodmap -pke > ~/.xmodmap

then in the file, I see

keycode 123 = XF86AudioRaiseVolume NoSymbol XF86AudioRaiseVolume

So it should be OK? How do I know what key is 123?

If you solved the issue, don't just mark it as solved and move on. You should post what you did so that other people (including yourself sometimes) may find useful.
