Keyboard and touch pad not working on HP convertible x360 with Ubuntu 19.10

Solution 1:

So after a long and frustrating 3 day, I managed to get the Internal keyboard and touchpad working.

My solotuition is as follows:

1. Edit the grub defaults, my personal option is $sudo nano /etc/default/grub
2. edit the line containing "quiet splash" to read "quiet splash acpi=off"
3. Then run $sudo update-grub and sudo update-grub2
4. Reboot the system and it sould be working fine.

Solution 2:

I had similar issues on my HP Envy 15-edxxx convertible running Ubuntu 20.04 (touchpad, touchscreen, pen, and audio not working). I upgraded the kernel to 5.9 and the issues basically fixed themselves, but 5.8 should be enough (you can test this with Ubuntu 20.10 live CD).

I suggest you a) Upgrade the kernel to 5.8 or higher. This isn't recommended, because the newer kernel versions may not be officially supported by your current Ubuntu version. b) Install Ubuntu 20.10 instead, which comes with the 5.8 kernel (according to this answer, there is not upgrade path from 19.04 to 20.04/20.10, which means you'll have to do a fresh install)

For a):

1. Check your current kernel version with uname -r
2. Download the mainline Linux kernel of your choice here. For 64bit architecture you'll need linux-headers-VERSION-NUMBER_all.deb, linux-headers-VERSION-NUMBER_amd64.deb, linux-image-VERSION-NUMBER_amd64.deb and linux-modules-VERSION-NUMBER_amd64.deb
3. Run sudo dpkg -i *.deb in the directory with the downloaded .deb files.
4. Reboot and enjoy :)

For b):

1. Backup everything you need.
2. Download the .iso here.
3. Flash .iso onto USB or CD.
4. Install the new distro with the configuration of your choice.
