Bug#840818: nvidia-driver: Breaks system on a fresh installed debian; Buggy, but overwrites nouveau driver

[Domonkos Lezsák]

Package: nvidia-driver
Severity: serious
Tags: upstream
Justification: Policy 1.1

After installing nvidia-driver on a fresh installed debian (or on it's distributions too), the driver could not be loaded causes to boot in low-graphics mode.
The main problem is here, that the package overwrites the xserver-xorg-nouveau driver and it's hard to be restored, even purging nvidia-driver and reinstalling/reconfiguring xserver-xorg-nouveau. For me, a complete new Debian installation was the solution.
The package was working earlyer on Linux Mint Sarah, but now breaks both system.
