Some keys don't work randomly

Today, for the first time, I encountered a problem where some of my keys stop working for a period of time and then resume functionality. The list of keys that stop working randomly are described below:

  • Left Ctrl (Right Ctrl is working without any problem).
  • Decrease Volume
  • Plus key +
  • Dash key -

I have already restarted the system, but the problem persists. Here is my system information:

$ uname -a

Old keyboard?

Switch to a console and login there by pressing CTRL+ALT+Fn Where Fn can be F2 or higher.
Then run this command to see if your Keyboard actually generates keycodes for those keys:

showkey
  • This command will only work in the console, not inside a terminal of your GUI…

If you don’t see any key-codes, it means those keys on your keyboard have hardware problems and there is nothing to do but let it be repaired if possible by your local hardware service.

If you don’t see any problems this way, but your problem only happens in the GUI, then you need to check your keyboard layout used inside the GUI.

PS:
To return to the GUI, you can most likely use CTRL+ALT+F1
