There is an NVIDIA Solaris Driver web forum. You can access it by going to devtalk.nvidia.com and following the "Solaris" link in the “GPU Unix Graphics” section. This is the preferable tool for seeking help; users can post questions, answer other users' questions, and search the archives of previous postings.

If all else fails, you can contact Oracle for support at http://support.oracle.com, or your local service provider.

NVIDIA provides a technical contact for information about potential security issues. Anyone who has identified what they believe to be a security issue with an NVIDIA UNIX driver is encouraged to directly contact the NVIDIA UNIX Graphics Driver security email alias, <unix-security@nvidia.com>, to report and evaluate any potential issues prior to publishing a public security advisory.
