[Nix-dev] no hardware rendering

[Berno Strik]

I've come a little bit further:

[bstrik at nixos:~]$ LIBGL_DEBUG=verbose glxinfo
name of display: :0.0
libGL: pci id for fd 5: 8086:2572, driver i915

undefined symbol: __driDriverGetExtensions_swrast libGL: Can't open
configuration file /etc/drirc: No such file or directory.

So apparantly it is a missing symbol. What is causing this?
