Hey, I'm following up with this in case anyone else runs across the same issue. I tried OSG on an installation of Arch Linux with the following setup:
kernel: 3.2.5-1-ARCH ATI driver: xf86-video-ati 6.14.3-1 package (I have an ATI Radeon Xpress 1250 card) OpenSceneGraph: openscenegraph 3.0.1-4 package And the cow.osg example works fine now.
