two different screen stop libnotify to work

[Lilian Besson]

1) On Ubuntu 11.10,
2) with notify-send 0.2.2 and the latest libnotify library (0.7.4-1).
3) with two different screen, the original one (of my laptop) and a second one (a Dell) linked with VGA cable.

     As soon as I'm launching my xrandr config script, all notifications based on libnotify are stoped. And then, any notifications are showed.
4) `notify-send "test"` return no error code, no warning message at all, but the notification is NOT printed, neither on the first or on the second screen.

Just for a reference, my xrandr script is :
xrandr --output VGA-0 --mode 1280x1024 --pos 0x0 --rotate normal --output LVDS --mode 1366x768 --pos 1280x256 --rotate normal --output HDMI-0 --off
