I installed 15.04, everything is running smoothly. One issue, however, is that I have no battery notifier on either gnome nor unity.

Q: How could I begin to trouble shoot this, if there is no fix, is there another app that I could install that will do the same thing?

First, check and see if you have a battery entry in /proc/.

ls /proc/acpi/

If the list you get back includes a 'battery' entry you can run:

cat /proc/acpi/battery/

Which will return the information on the battery.

Secondly, if the above ls /proc/acpi doesn't include an entry for 'battery' than you can install acpi with:

sudo apt-get install acpi

Once installed (you may need to reboot) you should be able to run:

acpi -b

and this will return the battery level information.

For more info on the acpi command, run man acpi

  • Thank you for this. Unfortunately, it's a kernel related issue. There are patches available which I'll explain in my answer. – Brandon Bertelsen May 13 '15 at 18:22

Github user neoreeps has been kind enough to include all the patchs, with instructions, in one place.
