I have a lenovo E335 thinkpad with Xubuntu 16.04. I have a problem that during typing, sometimes a key can get stuck. The keyboard freezes and continuously sends the last key pressed, eg. tttttttt or ffffff in the prompt.



Details:



  • the thinkpad's touchpad is disabled, the nipple-mouse is allowed.

  • during key-stuck, the nipple mouse freezes also, the usb mouse remains respondent.

  • I installed several versions in the past ~4 years on this machine, had this problem with all the ubuntu versions (other distros I haven't tried).

  • It might be some key-combinations but I don't find it.
