Comment 41 for bug 1584479

Hi,

I have HP Zbook 15 with NVidia+Intel graphics.
I have enabled NVidia to have better performance (discrete in bios).
This requires pnpacpi=off in grub, for Ubuntu to boot into graphic mode with nvidia drivers.

And I think this option also disables laptop touchpad and keyboard.
I don't see them in xinput.
Both of them work in BIOS and when you boot live image.

This all started with 18.04 and is the same in 19.04 and 19.10 with 5.3.0-19-generic

So, yes, this option is definitely a problem for laptops and nvidia drivers.

Any workarounds? Except using external USB keyboard and mouse...
