Help: "Error of failed request: GLXBadFBConfig"

Hi there,

I’m trying to work through this tutorial http://www.arcsynthesis.org/gltut.

I can compile the examples but upon running them I get the following output for all of the examples:


X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  34
  Current serial number in output stream:  33

I can’t figure out how to fix this. Any ideas?

Thanks,
David.
