I was looking at the software center and I notices that in Edit > Software Sources > Additional drivers there was an option to use the proprietary drivers for AMD cards. I've already tried looking at the proposed ways to install the proprietary driver and so far they involve a lot of blindly pasting commands and the risk of Unity not running/booting in low resolution mode, so I was wondering if those tutorials are outdated and using the software center is a viable alternative.
Also, I think it's worth asking if going through this will actually work with my card. I have an AMD Radeon H 7670M and an Intel 4000 HD if I recall correctly.
Thank you for your time
