Bug Description


 * All Dell Latitude and Precision computer users can not use the wlan/bt hotkey.

[Test Case]

 * Use any Dell Latitude and Precision computer to check the wlan/bt hotkey.

 * If you don't have the computer above, you can use the following command to check, and the expected output is "KEYBOARD_KEY_88=!wlan" instead of "KEYBOARD_KEY_88=!".

[Regression Potential]

 * No regression

[Other Info]

 * None

Just install the official Ubuntu 18.10 on any Dell Latitude or Precision computer and press wlan/bt hotkey on the keyboard.

I have verified systemd/239-7ubuntu10.5 but it doesn't fix this problem alone.
It also needs to install xkb-data/2.23.1-1ubuntu1.18.10.1 to fix the problem.
