Bug#680972: Nvidia driver 302.17 shows blank screen on resume from suspend or hibernate

[Viktor Radnai]

Package: xserver-xorg-video-nvidia
Version: 302.17-3
Severity: important
Tags: upstream

Dear Maintainer,

This issue affects unstable for now. The upstream nvidia driver version 
302.xx has an issue where the screen will remain blank after resuming 
with X with keyboard presses having no effect. The OS will run in the 
background and orderly shutdown is possible by pressing the power button.

See the following for details:

According to NVIDIA this will only be fixed in 304:

WORKAROUND:

Downgrading to nvidia-kernel-dkms and xserver-xorg-video-nvidia to 
testing (295.59-1) has fixed the issue for me.

Please consider creating a legacy 295.xx long-lived branch to allow 
easier downgrade.
