I wanted to try out the acceleration video mode from Adobe Flash 10.2. libvdpau1 ist installed and in /etc/adobe/mms.cfg EnableLinuxHWVideoDecode is set to 1.
But if I watch an example video I get "software video rendering". I uninstalled nvidia-current and tried the drivers from nvidia.com. The installation was successfull and a xorg.conf was created but after a reboot the desktop environment haven't started. I don't know if I need something other to configure because this was my first manual installation.
I reinstalled nvidia-current and rebooted the system. Now I got on the example flash video "accelerated video mode" and the performance increased heavily. I figured out this was because the manual installed nvidia drivers wasn't uninstalled. After I uninstalled them and rebooted the system I had again "software video rendering".
The xorg.conf from nvidia-current and the official nvidia driver was the same except that the official driver had the NoLogo entry set to true so the xorg.conf isn't the problem.
The question is how can I activate hardware acceleration on nvidia-current? Or is this only possible with the official nvidia drivers?
I'm using Ubuntu 11.10 dev and the version of nvidia-current in the repository is currently 270.41.06 (the same which is currently on the nvidia site).
