How can I get my battery info (percentages) on Fluxbox?

I've heard of the gnome-power-manager, and wanted to use that, but there seems to be a problem...

$ gnome-power-manager
gnome-power-manager: command not found

And when I try to install it:

$ sudo apt-get install gnome-power-manager 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gnome-power-manager is already the newest version.

I reinstalled it, and still the same situation! Apparently it's installed, but Ubuntu doesn't recognize the command. Also, I don't really like wmbattery, I'd like something that exists next to those applets and other icons (nm-applet, sound, Skype, etc).

I have highlighted the area I would like to have the battery information applet at:

fluxbox isnt a common WM - so it might help if you can add a picture as to your current desktop - where such an applet would exist, how have you installed other fluxbox applets. – fossfreedom Aug 3 '12 at 11:16
Other applets I already had. For example, simply putting nm-applet & in the .fluxbox/startup file gets me that network applet. – jcora Aug 3 '12 at 11:25
I would recommend adding gnome-power-manager into your fluxbox startup and see what happens, some forums I have read seem to suggest that works. Otherwise have you tried xfce4-power-manager? – Jacob Tomlinson Aug 3 '12 at 11:37
I haven't tried xfce4, but adding gnome-power-manager does nothing. – jcora Aug 3 '12 at 11:44

After researching this myself recently I settled on batti.

Batti is:

  • a very lightweight gtk app written in Python
  • easily installable from source
  • shows detailed battery information including time remaining when you hover over the indicator
  • Allows you to suspend/power off by selecting from the menu after a left click.

It's available from here.

Once downloaded and unpacked, simply call

sudo python install

Add batti to your autostart menu to have it load when you login - in your case just add it to your .fluxbox/startup file.

Some screenshots of batti in action (it's the battery icon, not the lightning symbol - that's jupiter power management applet):

Definitely half empty ;) Some useful info

Excellent solution. Just commenting to report that this work perfect in i3WM. Thank you very much! – Geppettvs D'Constanzo Sep 24 '14 at 19:16

I use the xfce4-power-manager

xfce power manager was not so nice for me: It promissed to suspend my netbook when I closed the lid, and failed to (which is annoying and a bit dangerous...) – josinalvo Aug 15 '12 at 13:54
