Wie verschiebe ich das Gnome-Panel zwischen Monitoren ohne den Gnome-Settings-Daemon in xmonad?

Question

Ich verwende xmonad mit Gnome-Panel, aber nicht mit Gnome-Settings-Daemon. Ich starte Gnome-Panel, indem ich es in xmonad.hs spawne. Wie kann ich (auf der Befehlszeile) Gnome-Panel dazu bringen, die Monitore zu wechseln?

xmonad.hs:

myManageHook :: [ManageHook]
myManageHook =
  [ resource =? "Skype" --> doFloat
  , resource =? "Vncviewer" --> doFloat
  , resource =? "gnome-panel" --> doIgnore
  , isFullscreen --> doFullFloat
  ]

startup :: X()
startup = do
  spawn "gnome-panel"

main = xmonad $ ewmh defaultConfig
    { modMask = mod4Mask
    , terminal = "gnome-terminal"

    -- avoidStruts prevents overlap with gnome-panel
    -- smartBorders disables border in full screen (or single-window)
    , layoutHook = avoidStruts $ smartBorders $ layoutHook defaultConfig
    , manageHook = composeAll myManageHook <+> manageHook gnomeConfig

    -- docksEventHook reworks windows whenever a dock gets in the way
    , handleEventHook = docksEventHook
    , startupHook = startup
    }
