numlock state always remembered when changed

[RaychoRaykov]

 * csd version: 4.8.4+ulyssa
 * Distribution: Linux Mint 20.1
 * 64 bit

Issue

CSD writes to disk on every press of NumLock.

Steps to reproduce

Press the NumLock and watch the disk operation indicator.

Use sudo inotifywait -m -e modify -r /home/user/.config/dconf to watch the realtime modifications:

/home/user/.config/dconf/ MODIFY user.FRBRZ0
/home/user/.config/dconf/ MODIFY user.FRBRZ0

Expected behaviour

There is an option in dconf: '/org/cinnamon/settings-daemon/peripherals/keyboard/remember-numlock-state', which should be checked before writing to dconf. I can't see any change of CSD behaviour when this option is enabled or disabled.

The actual code from the source file csd-keyboard-manager.c Line: 162 is:

	if (numlock_state != manager->priv->old_state) {
		g_settings_set_enum (manager->priv->settings,
				     KEY_NUMLOCK_STATE,
				     numlock_state);
		manager->priv->old_state = numlock_state;
	}

Other information

The same behavior can be seen on previous versions of Linux Mint / Cinnamon.

I solved my problem by commenting out lines from 155 to 168 and recompiling the package. I don't want to remember the NumLock state between sessions at all, so it works for me. But it's a workaround losing feature to remember the state if someone needs it.

It is still not addressed on Linux Mint 21.3 with Cinnamon 6.0.4.

The side effect is that every time you switch the NumLock ON or OFF, a file with size 200k is (re)writen.
