Ubuntu - GPU - VDPAU - Override the driver for VDPAU

The driver for VDPAU can be overridden by using the VDPAU_DRIVER environment variable.

The correct driver name depends on your setup:

For Intel graphics you need to set it to va_gl.
For the open source AMD driver set it to the proper driver version depending on your GPU.
For the open source Nouveau driver set it to nouveau.
For NVIDIA's proprietary version set it to nvidia.

Example

unset VDPAU_DRIVER
export VDPAU_DRIVER=radeonsi

NOTE:

The installed drivers are often found in /usr/lib/x86_64-linux-gnu/vdpau/ or /usr/lib/vdpau/.
- They are used as /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_${VDPAU_DRIVER}.so.

Some drivers are installed several times under different names for compatibility reasons.
- You can see which by running:
```
sha1sum /usr/lib/x86_64-linux-gnu/vdpau/*
```

For hybrid setups (both NVIDIA and AMD), it may be necessary to set the DRI_PRIME environment variable.
- For more information see PRIME.
