[SOLVED] vainfo hangs

When I try to run vainfo, I get some messages, then it hangs.
strace tells me it's waiting on a futex. Details below:

Linux ideapad 3.12.9-1-ARCH #1 SMP PREEMPT Sun Jan 26 09:01:37 CET 2014 x86_64 GNU/Linux

lspci | grep VGA

Re: [SOLVED] vainfo hangs

You have installed two wrappers. libva-vdpau-driver, which provides VA-API interface for VDPAU, and libvdpau-va-gl, which provides VDPAU interface for VA-API. Each tries to load the other.

Re: [SOLVED] vainfo hangs

I've removed 'libva-vdpau-driver' and the problem has been solved. Thanks!
