[Björn Daase]

I tried exactly the solution above using Ubuntu 16.04, but it does not
help. Does anybody have a clue?

Title:
  Logitech presenter only working partially

Status in systemd package in Ubuntu:
  New

Bug description:
  The Logitech R400 presenter's buttons for starting a presentation and
  toggling the screen to black does not work any more since at least
  Ubuntu 13.10 [1] (it had worked in a previous Ubuntu version I do not
  remember exactly and it still worked in Debian 7 Wheezy but also does
  not work any more in Debian 8 Jessie). The buttons for the next and
  previous slide still do.

  This presenter model has probably been one of the most widely spread
  ones since many years. I've bought mine in 2010 and it still is the
  best selling presenter on amazon.com and amazon.de. So really a lot of
  people are affected (moreover, similar Logitech models do exist, too).

  The problem seems to be in file /lib/udev/hwdb.d/60-keyboard.hwdb –
  the "displaytoggle" and "presentation" entries do not seem to be
  mapped to a key correctly (I do not understand how that mapping works
  in more detail). As a workaround, the Logitech R400 entry in this file
  can be changed (see attached patch) followed by

      sudo udevadm hwdb --update

  but it does not seem to be a real solution as other devices are
  probably affected, too. The real solution would probably be to get the
  "toggledisplay" etc. entries in this configuration file to be mapped
  correctly.

  latest Ubuntu version tested: 15.10
  udev package version: 225-1ubuntu9
