I’m running an Arch Linux on my Lenovo Y500 SLI Notebook (two GeForce GT 650M) with the latest 340.32-1 driver from the Arch repository. Kernel is running on version 3.16.0.
If I type after boot I can only read the first few lines of the xserver output and after that the whole notebook crashes. The machine simply powers itself off. Due to this fact it’s kind a hard for me to give you further debug information.
