 From what I can see at flightgear.org it does not require DRI, simply 
OpenGL.

OK : good think ! I was not sure, and on Fedora DRI makes all : without 
DRI the simulator does not start, with DRI it works fine.

In this case (DRI not really needed, e.g. on Solaris), the problem is 
for me other. Actually, with both X servers, the simulator starts, looks 
good, but very too slow. Same problem (but not so high) displaying 
NURBScurves in 3D modelling with Ayam.

Not yet useful for my Radeon 9200, and AGPgart crashes (frame) at the 
machine reboot.

Instead, i builded from a Mesa/DRI checkout r200 (AGP 8x) and glx (550 
fps) drivers, all works but same results with the simulator : starts, 
looks good, but very too slow.

And especially Ati ..? :-)

- In the fact, and since my mysterious problem with the simulator, it is 
also true that the native Xsun server, a little more as Xorg, provides 
yet a fine and fast display. Its also not impossible that the 
screenshoot with FlightGear, wich i saw on a Opensolaris homepage, comes 
from any sparc-machine with Sun videocard ?

OK : i thank you very much for your long and detailed answer.

Cheers,
