gnome-appearance-applet causes jockey to pop up again after enabling driver, but not rebooted yet

[Stephan7]

Binary package hint: gnome-control-center

After installing ubuntu 8.10 and updating it, I immediately added a video driver
using menu "System"->"administration"->"Hardware drivers" and selecting
the recommended Nvidia driver version 177.

The by pressing right-click on the desktop (gnome-appearance-properties)
and choosing tab "Visual Effects" I wanted to enable "extra".
This caused a popup that a video drivers was needed and pressing OK would
install it.. however I already had installed the video driver (although not restarted
the system yet) and so it did not detect this.
Further more after pressing Ok it indeed installed a video driver, but now looking
in the hardware drivers dialog showed it installed the Nvidia's non-recommended lower
version 172.

The "visual effects" proposal for video driver does not match the one from hardware drivers.
And it can't detect it already had a video driver installed.

Well, it says that you need to reboot, for good reason. To fix this properly, it would require jockey to return a new status code "enabled, but not rebooted", and gnome-appearance-applet to show this status.
