I have a Sager 8268-s / Clevo 150 running Ubuntu 14.10, nvidia 343 for
GTX 870M.
The screen freeze is guaranteed to happen. It seems to be triggered when
I am using the nvidia GPU and the touchpad. Using the Intel Graphics via
prime-select prevents the screen freeze. I don't know if touchpad
details would help with fixing this nvidia bug.
The touchpad is
