[Bug 1605433] Re: [Dell Alienware 17 R3] FN+F11 Enable/Disable touchpad not working

I'm completing the reports below:

3. $ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
[sudo] password for adin:
1.6.1

4. On kernel version 5.0.0-050000rc8-generic the problem persists.

* I also ran the previously requested `evtest` and got

$ sudo evtest

Title:
[Dell Alienware 17 R3] FN+F11 Enable/Disable touchpad not working

Status in linux package in Ubuntu:
Incomplete

Bug description:
The touchpad does not work as expected. It can't be enabled or
disabled through FN+F11 combination.

The light (in the pad) always turns on, regardless of its non
functionality.

The problem seems related to bug #1523738, and some say solution #24
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1523738/comments/24)
works, but it didn't for me.

WORKAROUND: Executing the following via a terminal allows one to disable and enable the touchpad:
xinput set-prop 13 "Device Enabled" 1
xinput set-prop 13 "Device Enabled" 0

But it only works if it is enabled from the beginning from the systems
configuration GUI. If it is disabled, it doesn't do the expected
behavior.
