My mousepad is not working after suspend on a Lenovo E460. It used to work perfectly but after this it no longer even appears in xinput. I have tried to plug in a mouse and that works fine. Edit: Restarting etc. does not make it work again, it is completely gone as of after the suspend.
Touchpad not working after suspend Ubuntu 16.04

Editing the grub file from, GRUB_CMDLINE_LINUX=   to,  GRUB_CMDLINE_LINUX=i8042.reset i8042.nomux i8042.nopnp i8042.noloop   then updating grub solved the problem.
