Comment 4 for bug 262491

I have setup multiseat configuration using following blogpost:

The setup uses Xephyr for separation of the virtually big Xorg xscreen. Unfortunately Xephyr does not support OpenGL. I have read somewhere that xserver-xgl does have such functionality. As it is no more available in Jaunty, what other XServer can be used, so that multiseat users would have OpenGL?
