This bug is for the xf86-video-qxl part of bug 770842. The required changes are to have xf86-video-qxl support a single pci device with multiple monitors as implemented by said bug.
For verification you need:
spice-vdagent>=0.12.0-2 (actually 0.12.0-1 will work too but a bug is fixed in 0.12.0-2 relating to arbitrary resolution & multiple monitor mode setting code, better check with it.
spice-server>=0.12.0-2
xorg-x11-drv-qxl: should be fixed in 0.1.0-1 but there were some build changes, I'm not sure the package was built correctly, so I used 0.1.0-2 as the fixed-in package.
