I installed Ubuntu 18.04.1 on my new HP laptop. The trackpad/touchpad does not work; it is not detected at all.

Both `xinput -list` and `less /proc/bus/input/devices` do not show any touchpad device. 

```
dmesg | grep -i pad 

```

also gives no output regarding to the trackpad.

I am aware that the laptop is very new, so I updated the kernel to 4.18.7 as well as 4.19.rc3 (the latest), but with no luck, nothing is detected. 

Sorry for my dumb questions, but what should I do in this case? Is this a kernel problem or an Ubuntu distribution problem? Where can I obtain support?

this solution does not work:
[Touchpad is not recognized](https://askubuntu.com/questions/525629/touchpad-is-not-recognized)

**UPDATE**:

As of linux kernel 4.19 stable, the trackpad is fully functional. Ubuntu user needs to manually upgrade the kernel to get it work, or wait until next point release :) cheers
