Power Management applet.

[LarryB1607]

Running LL 4.8.  I want to increase the time before the system goes to standby mode.  It is the mode after the display quits.  When I bring up the PM, it only stays on the desktop for about 1 second and then goes away.  Any other way to change these settings?

Thanks

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.

Thanks so much for the reply, I used the xfce4-power-manager -c command, but am still seeing the applet close quickly.  No explanation given.  Here is what I got from the other command.  Not sure where to begin.

cat ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-power-manager.xml
<?xml version="1.0" encoding="UTF-8"?>

<channel name="xfce4-power-manager" version="1.0">

  </property>
</channel>

I wouldn't advise making manual changes - it is hard to make sense of the raw files and too much risk of breaking their functionality without a working GUI.

I guess this alternate command to open the GUI also closes straight away without any errors reported ?

Code:

xfce4-power-manager-settings

Thanks again for the reply.  The reason I want to do this is my desktop screws up if I am away long enough for the PC to get to standby.  I have a 24" monitor attached to my 14" laptop. If I let the PC go to standby, the desktop splits into 3 sections.  The upper left corner is the desktop when I left it and the other 2 are the background.  I have tried a number of settings in display settings, even turning off the 14" and it still always happens.
