Ubuntu 12.04 amd64, Intel 965GM chipset.

Here is the result of vainfo command:

libva: VA-API version 0.32.0

libva: va_getDriverName() returns 0

libva: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so

libva error: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so init failed

libva: va_openDriver() returns -1

vaInitialize failed with error code -1 (unknown libva error),exit.

This file is actually exists, libva-intel-vaapi-driver is installed, even path to libva_driver is written to /etc/environment. I've tried to install those drivers with or without stopping the lightdm service, with bleeding edge Intel drivers or with standard canonical drivers, already. But have all the same result as at the beginning of the post.

update: after some research i have found that there is a non-zero possibility that VAAPI doesn't support GM965 (X3100) chipset. Is it really so?
