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.
