I'm having two issuses at the moment. I can't seem to install the Cinnamon interface through PPA and I'm missing the battery icon.
As far as the battery icon goes, I've tried adding pmu_battery using gksudo gedit /etc/modules but that didn't work.
I've tried adding the official PPA for cinnamon then updating the lists. When enter sudo apt-get install cinnamon, it says "Unable to locate package cinnamon"
I'd appreciate any help I can get. I forgot to mention I'm running Kubuntu 12.04
