I've been looking at other questions, but none seem to answer my query. The closest I got gave me information about a ppa for 12.04. My computer's battery life is suffering under Ubuntu 12.10. I imagine the performance will be better if I use LLVMPipe, as it is aimed at lower end computers. How do I enable LLVMPipe?
I might add that going back to 12.04 is not an option, as my computer only works in Unity 2D, which didn't quite do it for me. As far as I understand, LLVMPipe is pretty much the same as regular Unity. However, I can't seem to find much information about it. If this is wrong, correction would be much appreciated.
