I have a Lenovo X1 Carbon 5th, on startup the touch-pad works fine, I can click on something with one finger then drag it with the other.
After sleep I can only click but not drag...
I have the Synaptics driver installed, I have tried removing this but problem persists.
If I do this command, it fixes it but breaks the two finger scroll..
sudo modprobe -r psmouse && sudo modprobe psmouse
