--- Comment #4 from Felix Miata <mrmazda@earthlink.net> ---
Installed in a B85/Haswell/G3220 machine, the Cedar works as expected in
openSUSE Tumbleweed with kernel 4.2.1 and openSUSE 13.1 with kernel 3.12.44
using:
xrandr --dpi 120 --output DVI-0 --mode 1920x1080 --above VGA-0 --output VGA-0
--primary --mode 1680x1050 # ati dual
but using X600 or X1300, both displays go black.

With Fedora 23, Plasma 5 and kernel 4.2.2, with X1300 the 1680x1050 screen on
VGA-0 works as expected but the 1920x1080 screen on DVI-0 is black. With X600
and Cedar, all 1920x2130 works as expected.

Using
xrandr --dpi 120 --output HDMI1 --mode 1920x1080 --above VGA1 --output VGA1
--primary --mode 1680x1050 # intel dual
with the onboard video instead of X600, X1300 or Cedar, all OS/kernel
combinations tried run Xorg as expected.
