Keyboard input lagging in Linux Mint

Question

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?

Answer 1

Based on the information you've provided. It seems like you may be using a cordless keyboard. If so

• try using a different (USB) port
• move the "dongle" (if possible)

In any case

• If using a USB keyboard, move to a different (USB) port
• ALWAYS ensure that your keyboard is the ONLY device plugged into the (USB) port you're using

Answer 2

Try turn off USB port's power save option by setting autosuspend to -1.
