libva info: VA-API version 1.8.0

[azamet90]

using the latest kali linux and kernel version but this is what i get?

libva info: VA-API version 1.8.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit

the reason of im trying to install vainfo is that my videos playing laggy but i did installed my nvidia drivers and intel is even disabled... how can i fix that error i posted here?

va_openDriver() returns -1, suppose the entry function of nvidia_drv_video failed. could you help to check the return value of https://github.com/intel/libva/blob/master/va/va.c#L517
