Comment 5 for bug 768178

Since it is functionally equivalent, we recommend to only SRU a fix for this problem and not block the image generation for this bug.

The resolution path we are taking is to:
- first blacklist the nvidia-legacy driver for unity, and force a fallback to the classic session; for reference the nvidia-legacy driver was previously not compatible with the new xorg release
- then provide a fix as soon as we can design one

At install time, the users of such cards will have to download the driver in all cases. Either they will get a safe workaround, or a proper fix if available at this point.
