Comment 16 for bug 1273652

I have a similar issue with Ubuntu 14.04 (64 bits) and Nvidia driver 304.117 (please, refer to Bug #1388430 for details).
I spoke to Nvidia Customer Care support and they are requesting me to install another driver version (304.123) from Nvidia web site. Unfortunately, installation instructions are hard for me to follow, so I would need some help in order to test this driver version and give the technicians a proper feedback. If someone thinks that this could help to solve the issue, please feel free to e-mail me and I'll do my best to colaborate.
