Navigating nvidia's website, I found that the 750ti was officially suported starting from the linux driver version 334.21:
334.21 March 3, 2014 "Linux x64 (AMD64/EM64T) Display Driver" - Release Highlights http://www.nvidia.com/download/driverResults.aspx/73666/en-us Now, the newest driver package available for Trusty is: 331.38, and the newest nvidia package available for Utopy is: 331.89. They both work with my Geforce GTX 750ti card, though they are older than the first one to mention support for the 750ti (version 331.89 vs 334.21), and don't contain the matching modalias, so no driver is listed. I understand if us users cannot be recommended to run the available drivers for ubuntu, but I still think it is a bug to show an empty driver selection list in Additional Drivers, with no message to correctly reflect what is happening, or no possibility to select a 3D enabled driver by GUI, even if not the recommended one. In summary: My 750ti works perfectly with 331.38, and I think it is a bug not to show any drivers for selection even if not recommended, and not to give a proper message to us user. Instead we get just a blank list.
