The hardware accelerated openGL drivers cannot be accessed from X window, and there is no way we can change this. Basicalty, we cannot "teach" drivers writen by graphic hardware manufacturers how to draw in an X-window context. So you have to choose between: 1- Keep your app as is, using X window through GLX, and forget hardware acceleration. 2- Rewrite your app to use wgl and M$-specific functions to manage windows and input (this can be a substantial rewrite) and use hardware accelerated openGL for drawing. 3- Use some portable window management layer, like GLUT, and use hardware accelerated openGL for drawing.
