I'd like to add that I too am using regular gnome (ubuntu "classic") rather than unity. Unity doesn't perform well enough on my Thinkpad x100e to justify its use (bloated software -- I'm not impressed). Thankfully the old setup is still available. The Thinkpad X100e has a mobile Radeon card in it but I'm not using the proprietary drivers as the open source ones (default in Ubuntu for supported cards) provide better performance.
