You can render to a pixmap and then copy the contents of the pixmap to the window with XCopyArea(). This will be similar to many implementations of glXSwapBuffers, however, many GL implementation allow synchronization with the refresh rate, while Xlib offers no such feature. Note that glXSwapBuffers executes an implicit glFlush, while XCopyArea does not execute an implicit XFlush. Mark.
