Bug#775981: nvidia-graphics-drivers: nVidia bin drivers - Blank screen after install (EE: No screens found)

[Борислав Събев]

Hey, Vincent.

I was pretty sure that Optimus was disabled on my machine as I was using it
in single graphics mode for over an year and a half.
Thus, while debugging this, I did not check for the Optimus problems.
I checked and somehow it was enabled in BIOS (EFI). After disabling it all
is fine again and I managed to install the latest binary drivers.

I blacklisted the nouveau driver in a custom file in
/etc/modprobe.d/FILENAME::
  blacklist nouveau
  options nouveau modeset=0

Is there another way to remove nouveau driver without having to unisntall
the Gnome desktop? ( 'xserver-xorg-video-nouveau' is a dependency of
'task-gnome-desktop')

Thanks for your reply, Vincent.
I was so bummed that there was a bug that I didn't notice the
misconfiguration with Optimus.

As a conclusion this bug can be CLOSED as there is no issue.
It will for sure help other people as finding this out is not trivial.

Cheers,
  Borislav Sabev.
