I am running Ubuntu 13.04 and mobo Asus F2A55-M LE and Asus ATI Radeon HD6450 graphics card. My problem is the graphics card when installed I have two cloned monitors and I cannot change the view of the two. Is there drivers or any kind of software to correct this problem? I have always had Nvidia cards and I could always make adjustments but this one I can't. Thanks for your help.
