Proprietary Hardware Driver Activation Fails in Kubuntu 9.10

[Hinterland]

1. Click on hardware icon on first boot-up or selecting "Hardware Drivers" from the Applications->System menu.
2. Box pops up recommending activation of nVidia driver version 185 (in my case).
3. Click on "Activate"
4. Driver line in top box turns grey. Nothing else happens.
5. If left long enough (> 10 min), driver installation box disappears completely.
