Do you see any missing functionalities, such as some of the function keys/hotkeys not functional?

[Cristian Aravena Romero (caravena)]

Anthony Wong (anthonywong),

Hotkeys work 'all' right for the kernel "Ubuntu 4.18.0-11.12-generic 4.18.12".

Fix:
[ 15.133672] acer_wmi: Acer Laptop ACPI-WMI Extras

[Anthony Wong (anthonywong)]

Cristian, this message is harmless, kernel is just saying acer_wmi is not to be loaded because your machine is not an Acer.
