However, the performance is terrible with the AMD card.

I can run X, and I can even switch between the two cards. I was able to install AMD's Catalyst from the Ubuntu repositories and following these instructions from the AMD Linux Community's wiki.

The Intel card works as expected, apart from the occasional tear when scrolling or moving a window around.

This laptop comes with two graphic cards, an Intel HD Graphics 4400 and an AMD R7 M260. Almost everything worked great out of the box. I recently bought a Dell Inspiron 5547 laptop and installed Ubuntu 14.04 on it.
