Bug Description

After apt-get remove nvidia-* the file /etc/modprobe.d/nvidia-current_hybrid.conf remains and blocks the loading of the nouveau-driver.

So, Ubuntu works great, with 3D Unity and nouveau. Then I installed the nvidia-driver but didn't like all the consequences of that proprietary driver that doesn't integrate.
 - No proper Monitor detection (separate tool, forwarded to system as single monitor)
 - No color profiles
 - Ugly boot screen
 - etc.

But after uninstall of nvidia. It got me back to unity-2d, no 2nd Monitor (mission hdmi support)

I tried to reinstall nouveau, but driver still doesn't load.
Then I found out that the nouveau driver is still blacklisted. Manually removed that file, rebooted, it worked again.

There's a second file that blacklists nouveau, but gets removed after uninstall of nvidia-current. /etc/modprobe.d/nvidia-graphics-drivers.conf

content of /etc/modprobe.d/nvidia-current_hybrid.conf:

# This file was installed by nvidia-current
# Do not edit this file manually

blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off

This bug was fixed in the package nvidia-graphics-drivers - 295.33-0ubuntu1

nvidia-graphics-drivers (295.33-0ubuntu1) precise; urgency=low

  * New upstream release:
    - Added support for the following GPUs:
      o GeForce GTX 680
      o GeForce GT 630M
      o GeForce GT 620
    - Fixed a VDPAU bug where decoding some H.264 streams
      would cause hardware errors on lower-end products,
      resulting in corruption and poor performance.
    - Fixed a bug that caused DisplayPort audio to stop
      working after monitors are hotplugged on GeForce GT
    - Improved compatibility with recent Linux kernels.
    - Fixed a behavior change that prevented
      ConnectedMonitor from being usable with DisplayPort
    - Marked the GVO Clone mode NV-CONTROL attributes:
      as deprecated. They will be removed in a future
      release. To display an X screen over GVO, it is
      recommended to use GVO with MetaModes, instead.
    - Fixed a bug that caused DisplayPort devices to not
      be listed in Xorg.*.log.
    - Added support for 3D Vision ready displays that
      have a NVIDIA 3D Vision infrared emitter built
      inside the panel itself.
    - Fixed a bug that caused OpenGL applications to
      crash with some libc versions, such as eglibc 2.15
      (LP: #929384).
    - Fixed a bug that caused HDMI audio to stop working
      on AppleTV devices when an X server was started.
  * debian/nvidia-$flavour.postrm{.in}:
    - Make sure to remove the blacklist for hybrid
      graphics and to rebuild the initramfs (LP: #958848).
