Xmodmap, Am I missing something?

icelord · 2024-04-10 08:31:18

So I set my Xmodmap.conf according to the Archwiki recommended LQwiki.
I am using i3wm and I have alacritty installed.

After two nights of searching I caved in and have come to ask for help.

I am trying to set my multimedia keys which do not work, a printout has said that they were not assigned, so I assigned the XF86... for volume mute, sound up as well as volume down.
Since the changes my left and right arrow keys do not work and the sound keys still do not work either.
I am still a noob, are there any places there could be conflicting keybindings? I have checked all my .config files, and I have commented out the pulse audio within my alacritty config.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855

Post your .Xmodmap ("Xmodmap.conf"??) and the output of

xev -event keyboard

when pressing an arrow and the mute key.

Here is the xev of the mute button:

KeyPress event, serial 25, synthetic NO, window 0x2400001,
root 0x31d, subw 0x0, time 19941573, (-99,168), root:(588,186),
state 0x0, keycode 121 (keysym 0x1008ff12, XF86AudioMute), same_screen YES,
XKeysymToKeycode returns keycode: 113
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyRelease event, serial 28, synthetic NO, window 0x2400001,
root 0x31d, subw 0x0, time 19941647, (-99,168), root:(588,186),
state 0x0, keycode 121 (keysym 0x1008ff12, XF86AudioMute), same_screen YES,
XKeysymToKeycode returns keycode: 113
XLookupString gives 0 bytes:
XFilterEvent returns: False
KeymapNotify event, serial 28, synthetic NO, window 0x0,
keys: 29 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

And here is the xmodmap.conf:

keycode 113 = XF86AudioMute
keycode 114 = XF86AudioLowerVolume
keycode 115 = XF86AudioRaiseVolume

Please use [code][/code] tags, not "quote" tags. Edit your post in this regard.

The keycode is properly mapped, but not grabbed by anything (as shortcut)
If you expect eg. your desktop shell to grab the key, nb. that you'll have to finish xmodmap before that starts or it might grab the wrong code.

Okay thank you I shall remember that for next time.

So what you are telling me is I need to set each key with xmodmap or else it would cause an error?

seth · 2024-04-10 20:45:43

So what you are telling me is I need to set each key with xmodmap or else it would cause an error?

What? No.
You need to run "xmodmap ~/.Xmodmap" before whatever is supposed to grab the shortcut (eg xbindkeys) tries to grab the shortcut, otherwise the symbol will not be (properly) resolved.
The modmap itself clearly works, but you'r enot assigning XF86AudioMute to any global shortcut right now.

icelord · 2024-04-10 20:59:01

But that's the thing, I have done this already.

That's why I asked where any conflicts could be.

seth · 2024-04-10 21:00:26

Done what?
You're NOT binding that code to any global shortcut, but what do you think you've done *excatly*?

icelord · 2024-04-10 21:06:44

I did bind audio mute to key code 113?

Is there more that has to be done?

seth · 2024-04-10 21:20:59

You'll still have to bind it to some actual action.

icelord · 2024-04-10 21:22:56

Please can you explain this one a bit more, or send me a link to the wiki.

It's hard finding information, the page that guided me through the xmodkey setup didn't mention anything else.

seth · 2024-04-10 21:25:29

This has nothing to do w/ xmodmap, what is your desktop environment?

icelord · 2024-04-10 21:27:34

It's still basically a fresh install, all I have is i3, alacritty and firefox.

seth · 2024-04-10 21:52:29

https://i3wm.org/docs/userguide.html#keybindings
And then you bind that to some alsactl or pactl command

icelord · 2024-04-10 21:56:28

Thank you I appreciate the help, I will check it out.

icelord · 2024-04-10 22:00:25

Do I have to bind the keys through i3 as well? I had the idea that xmodmap was like a 'one ring to rule them all' of some sort?

seth · 2024-04-10 22:04:45

xmodmap links keycodes to key symbols and is typically not even necessary - 113 should be XF86AudioMute anyway.
It is not a shortcut daemon, those are provided by the WMs or desktop environments or dedicated like eg. xbindkeys/sxhkd

icelord · 2024-04-10 22:09:18

Oh I thought I was mapping keycodes to 'short cuts', this makes more sense now.

BTW, where did you see that the key was not being grabbed?

seth · 2024-04-10 22:11:01

grabbed key do not show up as key events in xev, you just get a keymapnotify event.

Okay, That is good to know thanks.
