[ubuntu] Unity doesn't work with latest amd driver?

view story

http://ubuntuforums.org – Hey everyone, I just got Steam, and downloaded a game. It took a while, then told me I need the latest OpenGL software for my driver. So, I went to amd.com, found my driver( for the Radeon HD 6570 ) and, not to mention I couldn't do a non-force install, whenever it finished installing, and I rebooted, Unity was gone. To expand on what I meant whenever I said non-force install, it told me I still had fglrx drivers in my computer and I needed to remove them, or optionally use --force. I did the whole sudo apt-get remove --purge fglrx fglrx-dev* etc.... and it still said I had fglrx drivers, (Hardware)
