The problem:

Since recently, on my Ubuntu 16.04, the keyboard keys don't repeat anymore and the touchpad tap and touchpad two-finger scroll don't work anymore.

The touchpad:

  • Tapping the touchpad, single and double, don't work anymore at all
  • Scrolling or zooming on the touchpad using two fingers doesn't work anymore at all
  • Moving the pointer with the touchpad still works fine
  • Both buttons below the touchpad work fine

Key repeat is all weird:

  • It repeats a key once between 5 to 10 times
  • It repeats the second key around 3 times
  • All following keys that are pressed for longer time don't repeat

Specs and info:

These screens show that the settings are there and set correctly:

Touchpad settings screen

Keyboard settings screen

These are my (relevant) specs:

System:    Host: jochem-ideapad-700 Kernel: 4.13.0-26-generic x86_64 (64 bit)
           Desktop: Unity 7.4.0
           Distro: Ubuntu 16.04 xenial
Machine:   System: LENOVO (portable) product: 80RU v: Lenovo ideapad 700-15ISK

This is the output of xinput:

I had symptoms similar to yours regarding keys but not touchpad.

The solution I found was from Fixing Keyboard repeat problems in Kernel 4.13. Check it out to find a more comprehensive guide and explanations.

Writing showkeys in a terminal showed that keycode 213 was being pressed and unpressed about once every second, explaining why keys held were being interrupted.

This is caused by the PEAQ WMI hotkeys module, that I see you have running too.

So to fix the keyboard

I typed in a terminal

sudo rmmod peaq_wmi

and verified that this fixed my problem temporarily. To keep the setting after the computer is restarted, I typed

gedit /etc/modprobe.d/blacklist.conf

and added the following to the file

#spams ^@
blacklist peaq_wmi

(Note: I do not know if this module was important to the functioning of my computer in any way. I will personally make a note that if something on my pc doesn't work I can try to re-enable it. I'll also check in a month or two to see if I can re-enable it because an update has fixed the issue.)

To fix the touchpad

according to the post you can try similarly

sudo rmmod psmouse
sudo modprobe psmouse

and if this fixes the problem until next time you restard, you can do

gedit /etc/rc.local

and add these lines

/sbin/rmmod psmouse
/sbin/modprobe psmouse
