Hardy Heron, nVidia and Desktop Effects

[Lelouch]

I have nVidia GeForce 7400. In hardy heron, the 'restricted' driver for my nVidia card is enabled but the 'In use' icon is red...

I tried to enable the desktop effects, but got 'Couldnt enable desktop effects' error

Should i install an additional driver?

Try entering this in a terminal.
$ sudo nvidia-xconfig -d 24 --allow-glx-with-composite --add-argb-glx-visuals --randr-rotation
Then restart X with Ctrl+Alt+Backspace. Save your work first.

Then you don't have the Nvidia drivers installed. :>

$ sudo aptitude install nvidia-glx-new nvidia-settings
$ sudo nvidia-xconfig -d 24 --allow-glx-with-composite --add-argb-glx-visuals --randr-rotation
