Toggling presentation mode via terminal. (xfce4-power-manager)

nemodlenec · 2019-01-18 12:35:48

Is it possible to toggle the presentation mode via a terminal? I'd like to bind it to a key in openbox.

Thank you.

Hello and welcome.

You can use:

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -T

The "-T" will toggle the setting between true and false.

Fantastic! Thank you and thank you for the welcome. Good to be here.

nemodlenec · 2020-05-01 18:52:22

Is there a command that will return the current state of the toggle?

If all you want to see is a true or false, this should do it:

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -v

Perfect! Thank you.

Hello, this is exactly what I was looking for, so thank you. It's great, that this can be turned into a shortcut.

Also, is there a way to have an icon or something, that sits somewhere in the xfce4-panel (taskbar), which shows the current status after the toggle?

I have never used it but xfce4-genmon-plugin should be able to do it. xfconf allows monitoring a channel, so for example, the following:

xfconf-query --monitor --channel xfce4-desktop

will keep watching the xfce4-desktop channel for changes.

Which version of xfce4-power-manager are you running? It should have an icon popup next to the battery icon when presentation mode is enabled:

I apologize, ToZ. That's way too off-topic but your panel icons are lit. What's the theme called?

From the VM with that screenshot, they are WhiteSur. The elementary-xfce icon set looks similar.

I am sorry, I've searched but I am not sure if I found the correct xfce4-power-manager version, the right-click on the battery icon shows version 1.6.6, but I am definitely not seeing that awesome flipchart icon

My xfce4 DE panel is 4.14.3 and looks like this:

no matter if the Presentation mode is on or off.
The only way I am checking if it's toggled is when I click the battery icon and the drop-down menu shows it.

Also it seems that it doesn't matter if the laptop is plugged in or not.

It was added in version 1.7.0. As a workaround, you could use the xfce4-genmon-plugin and a script like this:

#!/bin/bash

ON_ICON=emblem-mounted
OFF_ICON=emblem-unmounted

if [ $1 == "toggle" ]; then
	xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -T
	PLUGIN_ID=`basename $(fgrep -ri $(basename $0) ~/.config/xfce4/panel/genmon* | awk -F':' '{print $1}') .rc`
	xfce4-panel --plugin-event=$PLUGIN_ID:refresh:bool:true
	exit 0
fi

[[ $(xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode) == "false" ]] && ICON=$OFF_ICON || ICON=$ON_ICON

# do the genmon
echo "<icon>$ICON</icon>"
echo "<iconclick>$0 toggle</iconclick>"
echo "<tool></tool>"

...just change the ON_ICON and OFF_ICON variables to suit.

But can't I just upgrade it? I mean this came with my distribution of xubuntu 18.04 (updated to 20.04), which I initially installed on the previous laptop.
I just took the HDD after it died and I am now using it on this one, so I am not sure if this is the initial version of power manager, or it got updated somewhere along the way.
I am not on version 1.6.6 for any particular reason.

ToZ · 2022-01-13 21:23:12

Xubuntu 20.04 only packages up to 1.6.6 - you'd need to either upgrade to a newer distro version or enable some test/dev repository.

Thanks also.
xfconf-query --help and the docs unfortunately make us think that the command would be

xfconf-query -c xfce4-power-manager -p /presentation-mode -T

which doesn't work.

You need to be careful to get the correct path to the key. You can get the complete list of of keys with:

xfconf-query -c xfce4-power-manager -lv

...and there you can see:

...
/xfce4-power-manager/presentation-mode                  false
...
