The earlier bugs are gnome specific. The last bug is bad client behaviour and arguably lack of atomic modesetting support. xrandr is reporting a true limitation of the device in that the LVDS can only be bound to one pipe, so if you bind VGA first to that pipe, then LVDS cannot be lit. This is reported to the client via the available CRTCs so again doesn't appear to be a driver bug.

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->Displays, and even click on "keep configuration" but it doesn't activate. 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.
