PIGLIT_DEBUG doesn't print anything. All I get is:

X Error of failed request:  GLXBadFBConfig
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  34 ()
  Serial number of failed request:  22
  Current serial number in output stream:  20

I get the same error with gallium and classic swrast.
