When the laptop is either set to sleep by entering Fn-F1 or by timeout, the screen is black after waking it up again (using the power button, it does not wake by mousepad movement or key presses).
In earlier Ubuntu versions (14.04), a workaround was to enter a terminal console by hitting CTRL-ALT-F1, CTRL-ALT-F7, but that does not seem to work anymore.
The problem is is present in todays (2014-12-8) Vivid daily image (booted with "nomodeset", but not done any configuration of the screen).

Marius B. Kotsbak, thank you for reporting this and helping make Ubuntu better. Could you please advise on which NVIDIA driver version you tested specifically, and from what source (Ubuntu repository or nvidia.com)?
