I do not know whether this is of any use to you, but I have an Acer 
Aspire 5750G running Linux Mint Mate 21.3, on which, I run an external 
monitor, keyboard, and mouse, and, after reading the first post in the 
thread, I tried the keypad on that computer, and, it worked okay.

So, I think that it is not a Mate thing.

Perhaps, you could download the images for Ubuntu Mate 22.04 (and/or, 
24.04) and Linux Mint Mate 21.3, and  boot and run them as live images 
(rather than installing them), to find how your keypad works with them.

This is where using a Ventoy drive is useful.
