i have the same issue that i saw that many people here encounter before me.
i have asus k43sa laptop with amd hd6730m graphic card.
im trying to install the latest driver for mobillity (14.4) but just in the middle of the installation , the screen goes black and i cant see damn thing only by using an external monitor.
i have tried to clean uninstall the amd driver and to install 13.4 , but it didn't worked for me..
funny thing is that since installing 13.4 / 14.4 and not the 2011 driver from amd website, my system reconize the graphic card as 6740m ..
