Upgraded from 16.04 to 18.04.1 LTS.
Similar issue encountered where Fn keys are working (audio, mute, bright, volume and even wifi) except for enable/disable touchpad.
However, Touchpad disabled graphic is displayed (indicating recognition) but unfortunately has no effect i.e. not able to enable/disable using Fn key (Fn+F5).

Affected system(s): Dell Latitude 6400/6430

The Trackpad Hotkey continues to be recognized however the same 'Trackpad deactivated' graphic pops-up every time Fn+F5 hotkey is depressed. This is somehow not linked to the Enable/Disable Trackpad functionality in Gnome Control Center/Settings (i.e. does nothing).

Perhaps when moving to Gnome from Unity, this hotkey feature was not linked to the Trackpad toggle functionality? (Unless there's a hidden shortcut key to enable/disable the Trackpad)

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.19 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

No, they started in a fresh new installation (18.04).
Sorry, I can't test it anymore cause I changed to Deepin and, last month, I changed back to Ubuntu but I completely removed gnome and installed DDE as my window manager. So sorry.

Hi Joseph,

I can confirm this issue also occurred on a system that was upgraded from 16.04.

(a) Out of curiousity, are you actually able to enable/disable your touchpad on your laptop with Gnome on 18.04 using the key combinations (Hotkey) specific to your laptop?

(b) Does not seem to affect old Unity environments but never worked since upgrade to Bionic with Gnome now in use. Linux kernel likely not propagating hotkey event to the now in use Gnome-control-center (or Gnome-settings-daemon) package involved with acting on the hotkey event?

The latest kernels have also failed.

It's most likely some issue with the GNOME stack, but I have no idea how that one looks like these days on Ubuntu and I'm ETIME on figuring it out, sorry.

Deleting the synaptics driver resolves the issue.
It appears the driver needs to be deleted with the introduction of the libinput driver (now that the synaptics driver has been deprecated).

However this issue/bug occurred as the synaptic driver was not deleted during the upgrade to 18.04 from 16.04 (most likely due the the fact that the config file was not empty - however it would be impossible for it to be empty if it was the driver used in 16.04, prior to the introduction of the libinput driver with the 18.04 upgrade).

Suggestion: For all future upgrades to 18.04, there is the need to ensure the synaptic driver is removed to avoid breaking this functionality and introducing the conflict. If the user decides he/she needs the deprecated synaptics driver, they can always install it after.
This way, Ubuntu 18.04 and beyond would not appear defective in this instance after an upgrade.

Affects: Upgrades to 18.04 and newer.

Conclusion: This bug can be closed when this is fixed in future releases of Ubuntu.

I'm not sure who needs to be communicated about this, can someone please help to see this through to obtain a fix implementation and thus closure? Thanks.

Can confirm that removing xserver-xorg-input-synaptics fixes the issue.
