I recently installed ubuntu 18.04 on the HP Elitebook 1050 G1 and am running into issues with the clickpad.

When my machine first starts the clickpad doesn't work but if I put it to sleep, and wake it up it works fine.

I've seen other users run into this issue and have tried adding the following line to /etc/default/grub:

GRUB_CMDLINE_LINUX="i8042.nomux=1 locale=fr_FR i8042.reset"

I tried reloading the following modules without success:

  • psmouse

  • rmi_smbus

  • i2c_hid

Any suggestions?

I have the same laptop and here is my experience:

You need to have psmouse.synaptics_intertouch=0 in grub settings or else touchpad behaves like a slowly broken mouse and ubuntu 18.04 doesn't recognize it as a touchpad but a regular mouse.

  1. Kernel 4.18: First boot will not have a touchpad. Suspend once to get touchpad back but lose keyboard. Suspend one more time to get both keyboard and touchpad.

  2. Kernel 4.19/.20: First boot will have both touchpad and keyboard. However, after Suspend, touchpad becomes erratic and CPU for touchpad IRQ/snaptic constantly use 7% CPU draining battery and cause CPU to unable to sleep.

So 4.19/20 fixed boot issue but the CPU usage of touchpad IRQ after Suspend is killing me.

  • I haven't tried Kernel 4.19/20 but I switched to Fedora and it works great with both 28/29 Haven't noticed any CPU draining but ill key an eye out for it. Have you had any audio issues when plugging in headphones? I recall it playing from the rear speakers while headphones plugged in :o – D Sen Nov 30 '18 at 15:32
