Volume button

Jeebizz · 06-12-2018, 06:00 PM

I have noticed that the only environment that my volume button works is in MATE, if I go to LXDE or any other environment nothing happens when I press the volume buttons on my notebook, so how do I remedy that in making it more 'global' (if that is even the right term?).

Three separate problems need three separate threads, imo.

You are correct, but I was afraid of it being a bit spammy...

It won't be. Just edit this thread (including the title) to one of the topics, and create two new threads for the others.

I probably still won't be able to help with any of them, but I'll give it a go.

Ok I will edit and split into 2 more threads

I didn't think that the control of buttons like this was desktop environment-related, although I could well be wrong. Have you checked to see which code is actually being produced by the key in question and looked to see if that same code is perhaps being use by another application or the desktop environment itself?

Can I just confirm that this is happening on the same hardware running the same distro/version?

AFAIK it is environment related, because when I was fscking around with Ubuntu Mate and Lubuntu (live); the volume buttons always worked in Ubuntu Mate, but never in Lubuntu.

Both Ubuntu-Mate and Lubuntu were 18.04 btw

LXDE , what is LXDE? LXDE is an abbreviation for Lightweight X11 Desktop Environment, which sits on top of open box which is a highly configurable, next generation window manager with extensive standards support. But does it support volume buttons on a notebook?

You might be able to use them

Code:

keycode 160 = XF86AudioMute
keycode 176 = XF86AudioRaiseVolume
keycode 174 = XF86AudioLowerVolume

in openbox xml file for keybindings. or something simular, as well as each desktop/WM you'll have to set it up within each one seperately. By whatever means that DT/WM uses to control its keyboard settings.

The thing is, these aren't just different desktop environments, they're different distros (package setups etc.). What would be best is for you to have a test install of, say, Ubuntu MATE and then install LXDE onto that and switch between the two environments while testing the volume button, so that you're keeping as much the same as possible.

I see. Well I was hoping maybe I could get a clue on how Devuan (under MATE) was using the volume buttons by running dmesg after pressing the volume buttons but no luck.

I will have to try that for LXDE. I guess though I have to check specifically the docs for each environment I want then. Example if I decide I want to use XFCE, at one point or even GNUStep.

If you want to find out which code the button produces, try the following command in the terminal:

Code:

xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'

One other thing, I feel at least IMO that MATE itself is light enough for an i5 notebook with 8GB of RAM; even though MATE itself isn't considered 'lightweight' , I feel it would be compared to regular GNOME or KDE; though thats probably the only 'heavy' DE I might use. I do like LXDE a lot, but XFCE is also great but so far MATE is the only environment where my volume button just works.

Ok, I'll give that a go.

It would be interesting to find out why that is though, wouldn't it?

Nothing helpful came up when I did that though:

The event tester came up, but nothing was being shown when I was pressing the volume

I do not have the luxury of volume buttons that work on my laptop, I've been using my middle mouse wheel that works out rather well. there are two ways to set for volume changing that I'll seen.

if you search out the web you should find a way to get them to work. I do suppose.
