Fix blue Flash Player

With proprietary NVIDIA graphics card drivers, the flash player sometimes have a blue tint (for example on Youtube). This is caused by a bug in the driver. Below are two ways of fixing this. The second method is recommended.

The following is a simple work-around which fixes the blue tint, but may sometimes introduce some stability issues.

sudo mkdir /etc/adobe
echo -e "EnableLinuxHWVideoDecode=1\nOverrideGPUValidation=true" | sudo tee /etc/adobe/mms.cfg > /dev/null

If you have Ubuntu Precise, a better way of fixing it is to install a patched version of libvdpau. It can be installed with these commands:

sudo add-apt-repository ppa:tikhonov/misc
sudo apt-get update
sudo apt-get install libvdpau1

The patch that is applied to libvdpau 0.4.1-3ubuntu1 can be found here:
