You mean nvidia using this?:
Code:
sudo apt-get --purge remove nvidia-current
Yes, I did that (read the whole thread before starting my adventure).
But,
I think I figured it out.
You see, I removed the blacklisting of Nouveau:
Code:
sudo rm /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
and I purged it instead:
Code:
sudo apt-get --purge remove xserver-xorg-video-nouveau
apt indicated that it had successfully purged Nouveau an issuing the same command again confirms that it is no longer installed.
However, for some reason Nouveau seems to be loaded anyway!!!
So, I re-created the file the Nvidia installer created:
Code:
sudo nano /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
And inserted the original content:
Code:
# generated by nvidia-installer
blacklist nouveau
options nouveau modeset=0
Now VDPAU works; flawless HD playback.
It puzzles me why Nouveau is loaded after it has been purged (and it is not installed).
