You will need to find out what the keys trigger.
Do you see any messages in the journal when you press the keys?

Nothing in the journal.

 

Install "evtest" and try watching various sources to see if you get a
reaction when pressing the keys.

Nothing either. I tried monitoring the keyboard as well as the event fd called "LG WMI hotkeys", and those keys trigger nothing. :( Does this mean that it's a kernel issue?
