gnome-screensaver couldn't display unlock dialog

[Penk Chen]

While waking the system up from idle/screen off, the unlock dialog doesn't display, desktop beneath shown instead. Blindly type in password and press enter can still unlock the desktop, switch between virtual terminal and X brings back the dialog.

This happens because "gdk_window_raise" in gnome-screensaver couldn't bring up the unlock dialog, after upgraded xserver-xorg-video-intel-lts-quantal to 2.21.6 resolve this issue.
