You have been subscribed to a public bug: 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->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.
