As per request of lotuspsychje I updated my kernel from 43 -> 44.
This does NOT make a difference, bug still there.

Title:
Unable to toggle Touchpad by keyboard shortcut

Status in linux package in Ubuntu:
Confirmed

Bug description:
Pressing Fn+F5 button should toggle the onboard touchpad. This seems not to work and might be related to the following bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/717931

After pressing Fn+F5 shows the following:
$ dmesg
...
[ 248.412826] atkbd serio0: Unknown key pressed (translated set 2, code 0xf8 on isa0060/serio0).
[ 248.412833] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.
[ 250.261108] atkbd serio0: Unknown key released (translated set 2, code 0xf8 on isa0060/serio0).
[ 250.261110] atkbd serio0: Use 'setkeycodes e078 <keycode>' to make it known.

I've added the mentioned kernel parameters as described in
https://wiki.ubuntu.com/DebuggingACPI (adding acpi=off)
and
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/717931/comments/21 (i8042.nomux=1)
but the problem still exists.

Touchpad also has a little dot in the upper left side which I assume
also is for toggling on/off the touchpad. This is also unresponsive.


How reproducible:
Always

Steps to Reproduce:
Press Fn+F5

Actual results:
Touchpad is not working

Expected results:
Touchpad should toggle on/off, making it able to use the touchpad.

Extra info:
Bios is up to date.
