My trackpad stopped working after updating form Juno to Hera, now I'm forced to use a mouse.

system info

from my xinput list the touchpas seems to be recognized:

Virtual core pointer                        id=2    [master pointer  (3)]
Virtual core XTEST pointer                  id=4    [slave  pointer  (2)]
USB OPTICAL MOUSE                       id=10   [slave  pointer  (2)]
Synaptics TM3108-002                        id=12   [slave  pointer  (2)]
Virtual core keyboard                       id=3    [master keyboard (2)]
Virtual core XTEST keyboard                 id=5    [slave  keyboard (3)]
Power Button                                id=6    [slave  keyboard (3)]

Power Button                                id=8    [slave  keyboard (3)]
Sleep Button                                id=9    [slave  keyboard (3)]
Integrated_Webcam_HD: Integrate             id=11   [slave  keyboard (3)]
Dell WMI hotkeys                            id=13   [slave  keyboard (3)]
AT Translated Set 2 keyboard                id=14   [slave  keyboard (3)]
DELL Wireless hotkeys                       id=15   [slave  keyboard (3)]

I tried installing synaptic drivers which seemed to be missing:

sudo apt-get install xserver-xorg-input-synaptics

but that didn't solve anything.

Any help would be much appreciated.

I see you do not have the new Kernel tried to update it

$ sudo apt install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04

I think that will solve your problem, someone else also had this problem here

  • I just followed the link instructions and the kernel update worked like a charm, thank you!

  • You're welcome, it seems that with Hera it is necessary to update the kernel for the TouchPad to be functional.

had exactly the same problem. The above-mentioned didn't help. For me I had to install the synaptic driver from the terminal. Even I didn't need the driver before, I need it now..

apt-get install xserver-xorg-input-synaptics xserver-xorg-input-synaptics-dev-hwe-16.04 xserver-xorg-core

Before xinput didn't show the device. After installig the driver xinput shows it SYNA3602:00 0911:5288 Touchpad
