Hello

Sorry for my late reply.
Finally I had time to test your suggestion Richard.
The problem seems to be solved when I change the depth display of my X
server. I used always the 16 bit mode to get a good graphic performance with my old geforce card. I changed to 24bit but it`s a bit the nasty way, isn`t it?

Now I get some other errors with flightgear, but they have nothing to do with freeglut. I guess, I have to install flightgear from CVS sources (incl. openal). The old freebsd port seems to be broken.
By the way... the flightgear port from the portscollection points to libglut 6.0.1 (not freeglut).

http://www.freebsd.org/cgi/ports.cgi?query=flightgear&stype=all


But the makefile installs flightgear with freeglut. :)

Greetings  Karim
