I noticed after some use of the excellent LXLE distro on my Dell D430,
that there was no battery monitor installed by default. There is an
ASCII type monitor in the menu but not an applet, so I did a bit of
Googling and found this little how-to
for LXDE in Lubuntu/Mint. I had to modify that a little. I shall
reproduce the entire method here anyway in case that page disappears.
Install fdpowermon in the same way with:
sudo apt-get install fdpowermon
Next up it's slightly different since the sessions are different in
LXLE. There are 5 sessions: G2-Paradigm, Netbook-Paradigm, OSX-Paradigm,
Unity-Paradigm and XP-Paradigm so replace as appropriate.
gksu gedit /etc/xdg/lxsession/XP-Paradigm/autostart
Then append @fdpowermon as in the original how-to like so:
Save the file and exit, then logout and login and you'll now have a battery monitor applet, and we're done!
