@ curaga A summary of hardware
Among my PC's I have 3 with Nvidia video cards,
My main PC uses one of the latest Maxwell GM204 chips (out for almost a year) supported by driver v346.72
Other PC's use older hardware which are supported by the latest legacy 340.76 (almost all older Nvidia hardware are supported by this Legacy Linux driver)
Geforce GTX 560
Geforce GTX 260m
The legacy v340.76 is the driver we should be creating with kernel 3.16.6 to support all but the very latest Nvidia hardware.
The driver v346.72 supports the latest hardware
http://www.nvidia.com/download/driverResults.aspx/81760/en-usit is the Nvidia driver 346.72 in 3.16.6 on my latest hardware (which is fully supported by this driver) that fails the the config test, yet if built segfaults when installed
To assist, I have attempted to run Nvidia driver 173 on my oldest Geforce GTX 200 series hardware, so far without success. While I can not find more info on the NVIDIA-Linux-x86-173.14.39, I found NVIDIA-Linux-x86-173.14.30 info in the archives which supports the desktop version but not the mobile version of the hardware I have. The driver usually reports if the hardware is not supported, but not so in this case.
