No.

This message should probably be downgraded from an error.

I should, what can I do about it?  Does this have to do with the
command line parameters when starting the X server, for example?

This message indicates that we wanted to use direct, hardware-accelerated OpenGL ('Windows-DRI'), but that the server didn't allow it.

This could be due to:
- server option -nowgl
- windowing mode doesn't permit wgl (i.e. not -multiwindow)
- display driver does not support WGL (i.e. the default VGA driver)
etc.
