Displaying Battery Info in a Tint2 Panel
To display information about your laptop's battery in a tint2 panel, you'll need the following lines in your tint2rc config file:
# Battery battery = 1 battery_low_status = 10 battery_low_cmd = notify-send "battery low" battery_hide = 98 bat1_font = sans 14 bat2_font = sans 12 battery_font_color = #FFFFFF 100 battery_padding = 3 0 battery_background_id = 0
Using Ubuntu 12.04, my tint2rc is located at ~/.config/tint2/tint2rc. tint2 is a lightweight panel application that is a great match for window managers like openbox.
