Comment 218 for bug 982485

You can only attach one file at a time in Launchpad.

I'm not 100% sure if the updates should have automatically switched from nvidia-current to nvidia-current-updates, but I think they should have, base on other people's experiences (I don't own an NVIDIA card). Installing packages from the X Updates (x-swat) PPA may prevent this from occurring but you got a very similar package for that PPA anyway and it is working for you now, which is the main thing.

I understand that you have locked the driver version in Synaptic to prevent being downgraded back to 295.40. You may want to remove the lock when driver version 302.xx hits that PPA, install it and then lock the version again. 302.11 beta is available for testing now (but not in that PPA), the final 302.xx driver will have a higher version suffix.
