I have a strange problem with my newly installed Linux Mint 13 Cinnamon. Sometimes, while I'm typing, the system does not register some of my inputs. And sometimes, it gets 'stuck' on a key and repeats it 4-5 times and sometimes ignores 3-4 of my key presses after.

That's the best way I can describe it. Any way to debug this? Any fixes?
