Bug 73507

Since 2010, DRI2 supports multiple driver names. That was added to ease
selection of appropriate driver by libvdpau. As for today, intel driver
support only DRI2DriverDRI (== 0), but not DRI2DriverVDPAU (== 1).

Although there is no any hardware-specific VDPAU driver for intel video
adapters at the moment, it would be easier to use generic drivers like
libvdpau-va-gl by creating symlink named libvdpau_i965.so.1. That way
appropriate driver will be selected in run time automatically:
libvdpau_i965.so.1 on i965 equipped machines, and libvdpau_nvidia.so.1 on
nvidia equipped ones.
