systemctl restart keyd.service break the capslock mapping

[mcgaw]

Linux 6.8.0-49-generic
Ubuntu 24.04
keyd 2.5

I have a basic config:

[ids]

*

[main]

# Remaps the escape key to capslock
esc = capslock


# Maps capslock to escape when pressed and control when held.
capslock = overload(control, esc)

It runs as a systemd service.

When the computer starts everything seems fine.

However, when I reload the service it breaks. The capskey loses the tapping escape behaviour and regains capslock (although strangely the control behaviour remains).

The output from keyd -m remains the same.

I'm not sure how to debug further. The logs don't reveal anything (same for when starting with the system and after the restart).

Presumably it's to do with X running when the service is restarted.

(Incidentally, the reason I found this out is the keyd mappings just stopped working randomly, so I started looking at restart etc. Unfortunately I didn't capture any logs.)

The output from keyd -m remains the same.

Can you elaborate? Do you mean the output sequences are correct when you run keyd monitor? Can you post the output of the daemon itself?

Hi, yes, looking at the output of keyd monitor one would think that everything was working as per the config.

After the restart tapping the capslock key no longer functions as escape - but reverts to capslock.

I'm using a USB keyboard so I'll remove that from the equation and report back.

Edit: It doesn't seem related to USB keyboard.

Hi, yes, looking at the output of keyd monitor one would think that everything was working as per the config.
After the restart tapping the capslock key no longer functions as escape - but reverts to capslock.

So keyd monitor is still showing escape, but you believe capslock is being activated? If so, please post the output of both evtest and keyd monitor while pressing capslock after you have reproduced the problem.

[mcgaw]

Yes, keyd monitor is showing escape but in actual fact caps-lock is being activated.

I've attached output for before and after service restart.

I pointed evtest at the keyd virtual keyboard; I don't know if that's what you inferred. Thanks!
