I can't seem to get any indicators on my new installation of Ubuntu, I'm on a laptop so seeing the battery is pretty important, along with it just being a nuisance.
I've tried installing the indicator applet and using dconf, but they're still not showing up.
In case this matters, I had quite a few problems installing this distro, one being the 'low graphics' error, so I had to switch from lightdm then use proprietary drivers after that. Don't know if it's relevant but it might help.
Here's a screenshot of what it looks like.
