I wondered much the same about lxsession-default, in part because I want
to set the power button to actually just "Shut Down" as I have it set in
Power Preferences. Now, pressing the power button produces the logout
window, which I equate with "Ask."
So far I have not found any documentation for lxsession-default.
I made it part-way to the goal with "xset dpms force off." That just
turns off the monitor, but it does do so without root permission.

One problem solved: If I use "nmcli nm wifi on" and "nmcli nm wifi
off" instead of the rfkill commands, this toggles the wifi radio
without root permissions.
Now if I could find some suspend/standby and hibernate commands
that don't require root permission, this job would be done!

I spoke too soon. All the programs (rfkill, pm-suspend,

has allowed these keys to work as I intend.
I created /home/<user>/.config/openbox/toggle-wifi.sh with this
content:
#!/bin/bash
if [ $(rfkill list wifi | grep "Soft blocked: yes" | wc -l) -eq 1
] ; then
rfkill unblock wifi
zenity --info --text "Enabled wireless"
else
rfkill block wifi
zenity --info --text "Disabled wireless"
fi
And then:
chown root:root toggle-wifi.sh
chmod 4755 toggle-wifi.sh
I also tried inserting 'sudo command' in front of the rfkill
commands in toggle-wifi.sh, and I tried 'sudo command
toggle-wifi.sh' in the lubuntu-rc.xml command statement.

After thinking about it, I used an Upstart job to do what the

Though I'm no better than an Upstart hacker, especially with
regard to choice of a 'start on' event, I created
/etc/init/kb-keys-customize.conf with this content:
# kb-keys-customize

# Map key codes to the scan codes emitted by Fn-F4, Fn-F5, Fn-F12
description "Map Fn-F4, Fn-F5 and Fn-F12 kernel scancodes to

script
setkeycodes e017 128 e016 129 e018 130
end script
After rebooting, I found that 'xev -event keyboard' now reports
that Fn-F4, Fn-F5 and Fn-F12 are mapped to X keysyms Cancel,
Redo and SunProps, so I expect that I should be able to bind
those keys in lubuntu-rc.xml to Andre's suggested commands.

The next problem is that Fn-F4 and Fn-F5 don't generate any

To deal with that, I've been following the In-Depth
Instructions in
https://help.ubuntu.com/community/MultimediaKeys, and I have
identified the scancodes and picked a couple unassigned kernel
keycodes, but that article is old, and writing setkeycodes
commands into /etc/init.d/bootmisc.sh or /etc/rc.local seems
deprecated (those files don't exist).
Is there more current documentation for this task? Is
ibus-setup supposed to handle this job somehow under Lubuntu
14.04? Or is there another place preferred for auto-starting
setkeycodes commands?

Thanks, Andre, for all of those great tips.
I've been looking at the Exec lines in several versions of
~/.config/autostart/LXRandR-autostart.desktop (created when
one clicks Save in LXRandR) and thinking about how I could
create something that would cause Fn-F7 to toggle through the
LVDS, VGA and S-Video outputs, but your approach -- simply
binding to LXRandR -- is a MUCH better idea!
And if I wanted to add the ability to extend the desktop
instead of mirroring it, I could install arandr and just bind
to that instead.

*lxrandr* deals with additional monitors, you just enable
them an apply.
I'm not sure what commands you can execute to sleep and
hibernate, but you can control radio with *rfkill*. I'm
not sure if those commands really require root access,
but on that case you can do a: *gksu command*

Hope that helps! To test the shortcuts without restarting
all the system you can restart only openbox: *openbox
--restart*

Hi,
you can use arandr to make a shell script to switch
the display to a
certain mode. Plug in the monitor and use arandr to
make a setup you
want, and save that. Then open your config file for
openbox and set
the keyboard shortcut for your display key (i.e.
XF86Display)
to execute the
<command>
/bin/bash /path/to/scriptname.sh
</command>
while scriptname.sh is whatever you saved the setup
as with the correct
path.
arandr is a front-end for xrandr. So the script is
actually using
xrandr to modify your display settings.
I hope this helps.
