I recently updated the nvidia driver (x86_64) from an old 331.89 to the new 343.36 / 346.35 on Linux 3.14.30.
The problem is when start X, randomly it may fail because of nvidia driver fail. This does not happens many times, just really few times. There is no need to reboot the machine, just trying to start X again and works. I can logout X, login again and may or not fail, there is no pattern.
Note that with old driver (331.89) I did not experiment any issue on start X, always works all times and without any error during runtime.
