Even though 3D acceleration works fine and XFree86-DRI is loaded according to Xorg.0.log, I get the following output from vainfo:
libva: libva version 0.31.1
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib/dri/nvidia_drv_video.so
vainfo: vdpau_driver.c:189: vdpau_do_Initialize: Assertion `vdp_status == VDP_STATUS_OK' failed.
