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
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
