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.

    This is not the same bug as I stated, Their issue is with the pointer not being visible while mine is the entire touchpad is not being recognized. The workarounds for that bug does not work for me. – ADan Sep 14 '16 at 18:52
  • Did you suspend to RAM or suspend to disk (= hibernate)? – imz -- Ivan Zakharyaschev Feb 5 '17 at 23:41

Editing the grub file from,



GRUB_CMDLINE_LINUX="i8042.reset i8042.nomux i8042.nopnp i8042.noloop"

then updating grub solved the problem.

  • What does this fix do? I put it in /etc/default/grub and it fixed it for Fujitsu Lifebook T725, but I don't understand why it works now. Will it have any side effects? – Joshua Detwiler Jul 20 at 23:02
