Hi Russ,

as far as I know flightgear needs rendering software, just opengl.
At start it looks in its configfile, and tries to set the settings and initialising the scenery. IMO you MUST have an opengl-driver working ! Otherwise it will crash. Why does the nvidia-driver not work ? It should, if you use the Debian packages and compile the nvidia-kernel-module on your own, and, additionally install the package nvidia-glx.

Good luck !


 Today I upgraded to 2.6.17-2-amd64, used the debian Nvidia packages,
compiled nvidia-kernel-module, and installed nvidia-glx.  I made the
appropriate changes to xorg.conf (attached), added nvidia to /etc/modules, and restarted my xserver. As soon as I log in to gdm, the system locks up. I have to use ssh from another linux box to restart kill gdm. If I try to log in as an invalid user, it checks password, rejects the login, and gives
a new login prompt without locking up.  As soon as I successfully login,
the system locks up.
 I have reverted back to the vesa driver (again).  If anyone can help me
troubleshoot this problem, I'll be happy to reload the nvidia driver and
run whatever tests you can walk me through.  I'd really like to be able
to use the nvidia driver, for the performance boost it's supposed to
provide.  It also seems necessary in order to run Flightgear.

Thanks for any help.

I see from the xorg.conf file I attached that I tried to enable both the
vesa driver and the nvidia driver.  I corrected that, loading only the
nvidia driver.  The results were the same.
