Logs from "journalctl -b" as root

After updating to TW 20180129, pressing the following keys has no effect:

 * Power
 * Fn + F1 (suspend)
 * Fn + F3/4 (keyboard backlight)
 * Fn + F5/6/7 (display brightness and screen off)

All of these can still be controlled using the GUI, and all other Function keys
work properly.

Suspend and power button presses are logged by logind, however nothing other
action occurs, even after waiting several minutes.

This was a practically brand new installation with the 20180121 ISO and no
updates done before this one.
