Bug Description
Gnome-shell usually doesn't run on multiple monitors, even though it's configured in SystemSettings -> Displays
"usually" because once in a blue moon it does. So the hardware supports it.
xrandr lists:
LVDS1 connected (normal left inverted right x axis y axis)
1366x768 59.9 +
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
1920x1080 60.0*+
(other resolutions cut from the output)
gdm starts on both monitors. As soon as I log in, LVDS1 goes off.
I can enable the second monitor in SystemSettings-
It's disabled in software somewhere. I say that because the message tray at the bottom is in a different location when both monitors are active. So there is a software detect-monitor-size that moves the message tray, and it's almost always where it would be for single monitors.
Worked fine in Gnome-Shell 3.0.0.

This doesnt really sound like it would be a gnome-shell bug.
Does it work in Unity or Gnome Classic?
Does it work if you manually activate with xrandr, i.e. something like
xrandr --output LVDS1 --auto --right-of VGA1
Can you attach /var/log/Xorg.0.log and the full output of `xrandr -q` to this bug.
