I am using a Dell Inspiron 7559. I recently ran a large host of updates on my Fedora 26 installation. After this, the touchpad stopped working entirely, and does not show any settings in my GNOME 3.24 installation.

I understand that Fedora recently dropped Synaptics in favor of libinput. I made sure to uninstall the synaptics driver and remove the config files. Still, the touchpad is not working.

I think the issue is that libinput does not even see the touchpad. Is there some way to force libinput to detect my touchpad? Below is an output from libinput listdevices command:

Trying choosing the previous kernel from the boot menu. Does the touchpad work then?

It does not.

Does the touchpad show up in /proc/bus/input/devices?
