Xubuntu - Logitech presenter works only partialy
I have 2 old Logitech presenters, older and newer. Both worked under Ubuntu 10.10. Now I have Xubuntu 14.04 and older presenter works good, but new only partialy (only PgUp/PgDown, not F5 and dot.)
It's dmesg from new:

Older MODEL NAME: R-R0001.
Newer model name: R400
I had this same issue with my Logitech R400. From what I could tell, this is supposed to be handled in the file /lib/udev/hwdb.d/60-keyboard.hwdb. That file specifies button presses to catch and turns them into "standard" events like presentation and displaytoggle. But this isn't working properly in 14.04.
The comments in the top of that file tell you how to override it. So I followed the instructions and it worked! Below are the instructions I followed. I copied the section out and modified it to work like it does on Windows. These bindings work on LibreOffice Impress that comes with 14.04 as well as evince in presentation mode.
- Open your text editor.
-
Copy the following and paste into the editor.
# Logitech Presenter R400 keyboard:usb:v046DpC52Dd*dc*dsc*dp*ic*isc*ip*in00* KEYBOARD_KEY_070029=esc KEYBOARD_KEY_07003e=f5 KEYBOARD_KEY_070037=b Save the file as
70-keyboard.hwdb.- Open a terminal with CTRL+ALT+T.
- Change directory to where you saved the file, if necessary.
-
Copy the file to the appropriate place so that it overrides the bad entry and doesn't get clobbered by updates by running the following command. Enter your password when prompted.
sudo cp 70-keyboard.hwdb /etc/udev/hwdb.d -
Do udev magic so that our changes are picked up.
sudo udevadm hwdb --update sudo udevadm trigger /dev/input/event* It doesn't say so in the file, but I had to reboot before the changes took.
One note that I found important. Apparently, Windows doesn't use a single key to "toggle" into and out of presentation mode. F5 is used to begin the presentation and ESC is used to end the presentation. To give the effect of toggling presentation mode on and off, the remote itself first sends F5 then sends ESC.
So if the presentation has been started by you pressing F5 at the keyboard, pressing the "presentation" button on the remote will do nothing at first button press. It just sends F5 again. The second time you press the "presentation" button, it sends ESC and the presentation will end.
