ArchWiki says [1]: Catalyst does not support Xorg Server 1.15, check out #Xorg repositories and pick up xorg repository that you would like to use. According to the Xorg log, your version is 1.15. Try the open source driver xf86-video-ati instead of the proprietary Catalyst; see [2] for details. You will have to uninstall Catalyst first.
