Ubuntu 18.04 Cursor (touchpad) not working after "sleep"?

Question

ubuntu

Installed Ubuntu 18.04 on Lenovo Thinkpad T440p
And everything would be fine, but after switching the laptop to sleep and waking up, the touchpad does not work (the trackpoint and mouse also do not work), the cursor just freezes and does not move.
I found a couple of topics on forums and stackoverflow, followed the instructions, but nothing helps.
Maybe someone came across and knows the solution?

I had a similar problem with Ubuntu 14.04, which was solved by prohibiting updating the processor microcode.

sudo apt-get install intel-microcode=2.20140122.1
echo "intel-microcode hold" | sudo dpkg --set-selections
