Public bug reported:
I have Lenovo P50 laptop. After upgrading to 19.04 from 18.10 Synaptics
touchpad no longer supports scrolling after boot. It is also not
detected in 'mouse' settings.
After some research I found that running 'echo -n "reconnect" | sudo tee
/sys/bus/serio/devices/serio1/drvctl' seems to fix the problem.
Relevant info in dmesg:
```

```
This is a regression from 18.10 (and all versions before that that I've
run on this laptop).
Please let me know if more information is needed. Thanks.
