  1. These exact same things are happening to me too and also using a Lenovo laptop.


  • Just an extra for me this thing happens in only tty1 login when I press Ctrl and Tilde(~) button

  • Also freezes my keyboard and mouse when these buttons are pressed in GUI.

  • I tried booting from pendrive with a fresh Ubuntu 18.04 and this issue happened there too.

  • Tried with kernel 4.11 to 5.2.7 and this issue didn't solve.



  1. Have gone through this, tried blacklisting 'input_polldev', but didn't work
    https://bbs.archlinux.org/viewtopic.php?id=230340

Here is another same kinda issue-

Sorry that I couldn't write this in more details as my keyboard is troubling.
