Thinkpad Fix: Touchpad scrolling is not working after suspend

I noticed that after suspending my notebook, the thouchpad scrolling (at the edge or with two fingers) was not working any more. This seems to be a known bug Archive

My setup is:

  • ThinkPad T480
  • Ubuntu MATE 18.04

The linked comment above solved the problem for me:

You have to edit the file /etc/default/grub (sudo!) and change this line:

# from:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

# to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash psmouse.synaptics_intertouch=0"

Then apply the changes and reboot:

sudo update-grub
reboot
