Issue Selecting the preference "Disable touchpad when a mouse is attached," found under preferences->mouse and touchpad->touchpad, causes the touchpad to always be enabled, even when a mouse is attached.

Steps to reproduce 1) Go to Preferences->mouse and touchpad->touchpad. 2) Select the preference "Disable touchpad when a mouse is attached." 3)Plug in a mouse.

Expected behaviour The touchpad should be automatically disabled.

Other information When a mouse is plugged in, inxi returns the follow information about USB devices:

I find the same problem on cinnamon 6.0.4, installed on Ubuntu 24.04 LTS. Everything had been fine for years before the LTS upgrade. My working solution is to disable clicks on the touchpad using 'System Settings', then to disable the touchpad. I can use gsettings to re-enable if necessary - but a user dependent on GUI wouldn't be able to use this if the mouse was not available.
