Comment 17 for bug 1096457

I spent some time troubleshooting with Canonical support and while I still have this problem I was able to lesson it's probability of occurrence slightly.

I've done:
* unity --distro
* unity --reset-icons
* used jocket-text to list and purge all active NVIDIA drivers
* used apt-get to purge any lingering NVIDIA items
* used .xsession-errors to resolve a number of start-up issues
