jockey messed up with driver installation status

[Guillaume Bottex]

After activating the fglrx drivers with jockey, the activate button is still present (not changed into deactivate).
If I invoke a "jockey-gtk -l" command, the result for the driver is that it is disabled and is use.
So I cannot cleanly remove the proprietary drivers using jockey.

If I remove the fglrx drivers manually via synaptic, the X server will ask me to reconfigure my video driver when I restart.

Actually this bug happened after I played with envyng.

If I remember I tried to install fglrx via jockey, then install them via envyng and then uninstall them via jockey.
I am not really sure of the order, but I remember I did something that was sure to mess it up .....

So do you know how to make jockey correctly works again without a re-installation of ubuntu ?
I also reinstalled jockey but the problem is still here.
