What I did with my K2 was to appropriate the wire used for ALC in the K2-to-computer cable and connect it to the DTR pin of the computer's RS232 port. Then I added two Schottky diodes inside the K2 from this DTR line to the dit and dah inputs for the internal keyer. Finally, I set the menu parameter in K2 that allows a simultaneous paddle closure to act as a hand key input and told N1MM to use DTR keying.
With a paddle plugged into the K2's key jack I can use computer or manual keying at will. If your Linux logging program supports DTR CW keying, this is a simple solution.
