sound wheel and brightess keys not working

denispr · 2016-11-13 01:18

Hello Everyone,

I just installed q4os 1.8, very user friendly, nice job, thanks to all who worked on it !
I'm just facing a problem to get the sound wheel and brightness keys (Fn + F6 or F7) working on my Toshiba Tecra A10 11T laptop. None of them work, though xev shows that they are bound to :
XF86AudioLowerVolume / XF86AudioRaiseVolume for the sound wheel
XF86Stop / XF86Forward for the brightness keys

Strangely, for the brightness, I could partially work around the problem with trinity control center input actions dialog : binding XF86Stop to "xbacklight -dec 20" worked, but binding XF86Forward to "xbacklight -inc 20" did not.

Thanks for any help,

regards

Denis

Take a look in Regional settings in Control Centre - Keyboard Layouts is where you want to be. You may need to tick to enable - have a look and see if there is a generic Toshiba in the list that may work. Sorry, not on Q4OS right now so cannot provide blow by blow steps.

Also, take a look in Synaptic - just search for Toshiba - I do recall seeing some make specific stuff there which may help.

Thanks for your quick answer.

The keyboard layout I use is the same I use on Mate desktop where it works, so I guess the problem is somewhere else (and there is no generic toshiba keyboard in the list, only toshiba satellite that does not work).

I'll search in synaptic for Toshiba and let you know.

We would suggest you to run in terminal:
$ sudo apt-get install keyboard-configuration
$ sudo dpkg-reconfigure keyboard-configuration
select keyboard configuration as closest as possible.
$ sudo systemctl restart keyboard-setup.service

Thank you for your suggestion, I tried that but unfortunately brightness keys and sound wheel still don't work.

As I mentioned above, since that same keyboard configuration and layout works on a Debian install with mate on another partition of the same computer, I don't think it's a keyboard configuration matter.

It looks more like TDE fails to deal with XF86AudioLowerVolume / XF86AudioRaiseVolume / XF86Stop / XF86Forward X events.

Do you have a Q4OS installed laptop where brightness keys and sound wheel work ? If so, can you tell me, using xev, which events are bound to these keys / wheel actions ?

Thanks in advance,

Denis

Please try to assign a temporary keyboard shortcut for audio volume control to test it. Open 'kmix' sound mixer -> Go to Setting -> Configure Global Shortcuts -> assign 'Alt+D' for example to 'Increase Volume ...'. Then watch kmixer window and try to change volume with the previously defined 'Alt+D' key shortcut.

Next, run 'xev' and put here the output when the sound wheel position changes. We will try to check that.

Here is what I tried :

1) assign, the way you told, "Ctrl+Alt+ Page Up" to increase volume and "Ctrl+Alt+Page down" to decrease volume => shortcuts don't work, volume stays unchanged

2) xev output for sound wheel :

- increase volume (just reporting the end of the output which seems the relevant part of it) :

Just as a note, I found my screen brightness buttons (Fn F11 F12) did not work, then found that I could use my mouse wheel when hovering over the TDEPowerSave icon in the system tray to do it. But my volume buttons (Fn F1 F2 F3) work correctly.

We have tested shortcuts on a fresh Q4OS 1.8 installation in virtualbox, chosen simple keys combinations, 'ctrl+q' volume up, 'ctrl+z' volume down, 'ctrl+m' mute, all worked correctly. We have also tested 'ctrl+alt+page up' and 'ctrl+alt+page down' keyboard shortcuts on a real hardware with full software profile installed, that worked fine as well. So concluded you should get keyboard combinations to work in general first. Unfortunately, we are not able to reproduce the issue on our hardware, if someone else noticed similar issue, please mention it here, any additional info is appreciated.

2. The 'xev' output looks fine, as it should be.

Sorry I was wrong, Ctrl+Alt+Page up or down works, but only if I have first clicked on kmix applet to get the kmix slider viewed. Is this the expected behaviour ?

If so, I'd like to have a solution that keeps me from having to click on kmix applet to change volume. I noticed that, when I play music on vlc, the sound wheel works, but not with kaffeine or firefox (youtube).

q4osteam · 2016-11-14 21:17

We will perform some additional testing and answer a bit later, please be patient.

denispr · 2016-11-14 21:21

Thanks !

By the way, one more test I performed :

replacing "Cltr+Alt+page Up / Down" with "XF68AudioRaiseVolume/XF86AudioLowerVolume" in kmix global shortcuts dialog does not work : after clicking on kmix applet to make the slider appear, turning the sound wheel does not make the slider move, unlike pressing Ctrl+Alt+Page Up/Down before

No it's not. Unfortunately, we are still not able to reproduce this issue on a real hardware, 'Ctrl+Alt+Page Up/Down' works fine here, with kmix slider hidden in the system tray even with youtube firefox videos playback. If someone else observed the issue described above, or is able to reproduce it, please mention it here, any additional info is appreciated.

We would need get keyboard shortcuts to work in general first, in order to deal with the related hardware specific issues. Anyway, thanks for the reporting.

We will try to perform more testing and post information here as soon as a new findings are available.

OK, thank you.
