'''Note:''' While you should normally get to see something like "''direct rendering: Yes''" indicating working hardware acceleration, this doesn't have to be the case if you are running an OpenGL X server such as Xgl-still hardware acceleration may be working. However, it is important to realize that running OpenGL applications on top of current Xgl implementations may rather '''severely''' affect overall application performance, in fact FlightGear may be slowed down by a factor of 2.5 or even more, in addition more complex OpenGL features may not work as expected. So if you are using an GL-accelerated X-server (i.e. to run Compiz/Fusion) under Linux and are experiencing performance issues or other graphics related problems, please verify if these problems persist after having disabled Xgl support, this can usually be accomplished using xgl-switch --disable
