Add catalyst + xorg114 pacman repos to your /etc/pacman.conf:
[catalyst]
Server = http://catalyst.wirephire.com/repo/catalyst/$arch
[xorg114]
Server = http://catalyst.wirephire.com/repo/xorg114/$arch
Install required xorg server and driver packages:
xorg114/xorg-server
catalyst/catalyst-hook
catalyst/catalyst-utils-pxp
catalyst/lib32-catalyst-utils-pxp
xorg114/xf86-video-intel
extra/intel-dri
multilib/lib32-intel-dri
