Was told by support to download and install Nvidia driver 378.66 since it is the most 'stable'.
Currently have 'latest' version 381.09
But have 'issues'
Houdini crashes on launch and or certain GPU dependent plugins don't render.
Problem is I don't see v 378.66 in my Software&Updates (Ubuntu Mate 16.04)
Closest version is 378.13
Using this additional PPA for driver downloads

Where can I download 378.66 for Ubuntu?
