I have an Optimus laptop but I decided not to use optimus at all and just run with the nVidia card all the time. I wanted to get hardware video acceleration running according to the wiki (https://wiki.archlinux.org/index.php/Ha … celeration). However, it definitely does not work:
$ vainfo
libva info: VA-API version 1.1.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/dri/nvidia_drv_video.so
libva info: Found init function __vaDriverInit_1_0
GPU at BusId 0x1 doesn't have a supported video decoder
fish: “vainfo” terminated by signal SIGFPE (Floating point exception)
$ vdpauinfo
display: :1 screen: 0
GPU at BusId 0x1 doesn't have a supported video decoder
Error creating VDPAU device: 1
Some additional info that might be of help:
$ lspci | egrep 'VGA|3D'

The card has the E feature set according to https://en.wikipedia.org/wiki/Nvidia_Pu … _SIP_block so VDPAU should be available. Any help is welcome.

Same error with MX150, using nvidia driver. vainfo, vdpauinfo, nvidia-settings all say
GPU at BusId 0x1 doesn't have a supported video decoder
Have you worked it out?

Nope . To be honest, however, I haven't actually searched for a solution very much.

install bumblebee and use optirun?

If you were to use that you are better off using the intel GPU and VAAPI
Set VDPAU_DRIVER and likely DRI_PRIME=1 as well and check back how it behaves: https://wiki.archlinux.org/index.php/Ha … ring_VDPAU

I'm confused. Are you talking about using bumblebee or not? Not using it, setting DRI_PRIME=1 did nothing.
I'd rather not use bumblebee because it causes some problems for some applications I'd like to use (mainly games) and also the performance is somewhat decreased compared to using the NVIDIA card directly. But to be honest, this vdpau issue starts to drive me crazy a little bit so I'm considering going back to bumblebee.

I'm talking about not using it. My first sentence was a response to Xigi.
This is either way a bit of a special situation, since you have to copy the image over the intel GPU anyway, however afaik at least the decoding should still work
