     No!

     I  have looked at the above and run amaya under gdb with the --sync
argument.  The XWindow problem arises in glXMakeCurrentReadSGI after
stepping 62 instructions - when the X11 major code 143 (the SGI-GLX opcode)
is in the rsi register. One more step and the Xwindow error is reported.
The last instruction executed loaded rdi with the hex value 0x315e780 - if
that is any help to you!

     As to configuration of the machine -

     Mother Board - ASUS M2N-NX
     CPU - AMD Athlon x2-64
     Nvidia MCP61 revision 162  nForce 430/GeForce6100 chip set.
     Linux SuSE version 10.2 (kernel 2.6.18.8-0.3)
     X11 version 7.1.99.902

     The file /etc/X11/xorg.conf has the following modules loaded - dbe,
type1, freetype, extmod, glx, v41.  There is also the following section
which might be of relevance -

Section "DRI"
  Group "video"
  Mode 0660
End Section

which seems to indicate that DRI is running. I note, however, that the mode
is different to the one given by one of the correspondents in the reference
(which was 0666).

     Note that it would probably be unwise to edit this xorg.conf file as
it is automatically generated by the SuSE SAX2 application during initial
installation.

     I don't know whether the following is relevant, but since my original
report, when using VNC from another machine there is a warning (not error)
from xgamma in respect of X11 Opcode 134 (XFree86-VidModeExtension) -
immediately after logging in at the other machine.

     At the moment that is all I can think of which might help in tracing
the problem. Please ask if you think there is anything else I can help
with.

                    Keith
