Numlock key is double-registering and therefore not working

[moghingold]

Host: Mac OS with Barrier
Client: Arch Linux with KDE backend

Here is the debug output from waynergy when I hit the numlock key a single time on the host machine's USB keyboard:

405.301278698: [DEBUG] Modifiers: depressed: 10 latched: 0 locked: 10 group: 0

I'm not sure why this is double-registering or what to do about it. Currently, as you might expect, the numlock key effectively does nothing and I cannot activate it.

Here the corresponding debug log bits for barrier on the server side would be useful, at least for now (I should probably add a provision for more information to the waynergy logging to prevent necessitating this).

Thank you for reporting these issues, by the way; it is extremely useful to get data points for configurations I don't really use myself.

I can't figure out how to get useful debug output from Barrier when I hit keys on the keyboard. I can get it to show me when the mouse (and thus its focus) leaves and enters each connected screen, or grabs the clipboard etc, but not show output on each keystroke the way waynergy does. Do you know how I can get you the information you're asking for? Right now the debug output on the Barrier side when I hit the numlock key is, effectively, null

[moghingold]

I think I got it:

[2023-02-28T09:33:56] DEBUG1: onKeyDown id=0 mask=0x0000 button=0x0048
[2023-02-28T09:33:56] DEBUG1: send key down to "badvertising-ll" id=0, mask=0x0000, button=0x0048
[2023-02-28T09:33:56] DEBUG1: onKeyUp id=0 mask=0x0000 button=0x0048
[2023-02-28T09:33:56] DEBUG1: send key up to "badvertising-ll" id=0, mask=0x0000, button=0x0048

It does not seem to double-register the button-press on the Mac.

waynergy --loglevel debugsyn should now present the relevant information in latest master, though it's useful to know that barrier doesn't think it's sending a duplicate at least.

Here's what I got when I hit numlock:

For some reason Barrier is duplicating the button, while sending with a key id of 0, which probably shouldn't be happening.

In any case, a workaround. In new latest master, keys should now be dropped by mapping to -1, so disable one of the ids in a new section in config.ini:

[id-keymap]
61311 = -1

This is a simpler variant of what I'd posted earlier, which makes things slightly less confusing.

That fixed it!
