Comment 636 for bug 752542

HP Pavillion 15-e027sl
Hybrid amd enduro radeon hd 8670M / Intel HD 4000 (i5-3230M)

Tested on Fedora 19 up to date.
Fglrx 13.8 beta (rpmforge packages) don't work (aticonfig --initial say device not found, obviuosly after loading fglrx kernel module and blacklisting radeon module).
Radeon open drive seems to not be supported:

$ xrandr --listproviders
