Power Management applet.

[stevef]

The settings are saved in xml files located in your home directory.  Power management settings are in this file and can be listed with cat.
For example

Code:

cat ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml

There is a CLI tool to access and set values in these files - take a look at 'xfconf-query'

To try to find out what is going wrong with opening the utility itself try opening the power manager customisation GUI from a terminal session

Type or paste in

Code:

xfce4-power-manager -c

followed by enter

This should open the application window and if something odd is happening that closes it after 1 second there may be an indication in the terminal.
