xserver-xorg-input-synaptics in Bionic 18.04.2

Asked by Jaime Cruz

After installing the HWE for Bionic, I see that xserver-xorg-input-synaptics has been uninstalled. I needed this so I could disable the touchpad on my Thinkpad (I use the trackpoint, and I find it annoying that if I rest my hand the wrong way, the mouse pointer jumps all over the screen with the touchpad enabled).

I tried to reinstall it, but doing so would apparently remove the Unity Desktop Environment, something I DEFINITELY don't want to do. Is there some way I can disable the touchpad without having to uninstall Unity?

I assume that you have to use a specially designed xorg-input-synaptic package.

For diagnostic purposes please provide the output of the commands

uname -a
lsb_release -crid
hwe-support-status
apt-cache policy xserver-xorg-input-synaptics xserver-xorg-input-synaptics-hwe-18.04
apt--simulate install xserver-xorg-input-synaptics
apt--simulate install xserver-xorg-input-synaptics-hwe-18.04

Thank you! I suspected as much when I sent you the information but I wanted to wait for confirmation before trying. I installed it and at first didn't see any difference but then I remembered I had to log out and then back in and it's working perfectly.
