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.
- Utah-GLX - hardware accelerated open source OpenGL, but I don't
know the current status (their web page mentions a migration to Mesa
taking place in June 2003 as current status) -
http://utah-glx.sourceforge.net/
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.
2) Can i build myself an Opensolaris kernel with a DRI entry ?
If you port DRI to it yourself. There's already a team in Sun's kernel
group working on this though, so it would be duplicated effort. This
will
allow use of the Mesa/DRI drivers for open source hardware accelerated
OpenGL on a number of cards. It still won't be as accelerated as any
of the proprietary/closed source solutions though, since the video
chipset vendors don't release all the information necessary to do so.
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,
Sergio
