SDK Demos fail

I have managed to get libstdc++ onto my beagleboard by downloading the
ipk's from http://www.angstrom-distribution.org/feeds/2008/ipk/glibc/armv7a/base/
onto sd card and installing them using opkg.

Now I have the following problem when testing the PowerVR SDK Demos
(e.g. Raw/Demos/Shaders/OGLES2Shaders)

PVRShell: EGL 1.4
initialized
Exit message has been set to: "PVRShell: Unable to create
surface
".
InitAPI
failed!
PVRShell: Unable to create surface

Any ideas?

What does 'lsmod' return?

I found a solution:

I changed /etc/powervr.ini to
[default]
WindowSystem=libpvrPVR2D_FRONTWSEGL.so

Now it Works!
