Mint 21: Keyboard repeat settings ignored when USB keyboard attached

[endlisnis]

I have a non-default repeat delay set on my keyboard (I set it using the standard keyboard settings app in Mint). I've been using this setting (which is a smaller delay before the repeats begin) for many years with Linux Mint. I recently upgraded to Mint 21; but now I've run into a problem.

If I disconnect and then reconnect my keyboard, it reverts back to the default delay before the repeat begins. The keyboard settings app still SHOWS the setting I want, but it's not how the keyboard behaves. If I disable and then enable the repeat option using the keyboard settings app, everything works correctly.

I switch my keyboard between a Linux Mint machine and a work laptop every day, so I'm confident that this used to work and now I must disable and re-enable the setting every time I plug the USB keyboard back in.

Also, I use an accessibility setting "Control the pointer using the keypad". This also stops working if I unplug and then replug the USB keyboard. Hitting the numlock key a couple of times seems to make it start working again.

I'm pretty sure I was using the 5.15 kernel with Mint 20 before the upgrade, so I don't think it's a kernel problem.

Do you say, that it worked as expected in LM 20.3? I am not sure about this.

Open Users & Groups and create a new account for testing. Reboot and log into the new account. Test the problem there.

[endlisnis]

This worked as expected in Mint 20.3.

I just tried your suggestion, but I can reproduce the problem using a new user as well.

I created a new local user account "test". I rebooted and logged in as test. I changed the delay before the keyboard repeat to as low as it would go. Checked it (it was working); then I pulled the USB cable for my keyboard, and then put it back in. The delay was back to default, even though the settings app showed a non-default setting. Toggling the setting in the keyboard config app restored the delay.

A bug?

Boot the live system with Mint 21 and check, how it behaves there.

[endlisnis]

I tried booting a live USB Mint v21.

I was able to reproduce the same problem there (and even on a different desktop computer). Oddly, that system had both a PS2 keyboard and a USB keyboard on it. The problem was only reproducible on the USB keyboard. The PS2 keyboard repeat worked fine.

This confirms my suspicion. You can report it here: https://github.com/linuxmint/cinnamon/issues

[endlisnis]

Thanks, I reported the bug.
