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
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
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.

Hi Russ,

this looks strange for me. I suppose, you did use the original Debian packages and not the one from the Nvidia homepage. Those will not work.

The other thing is, you could comment the line >> Load "glx" << out, so that you will start withe the "nvidia" driver, but will not have acceleration. Another way is to use the driver "nv", which is the framebuffer driver for nvidia-cards.

O.k., if the "nvidia" driver works (which I suppose), then reactivate Load "glx". Take a look in /var/log/Xorg.log, there yxou may find some more information.

After building and installing the nvidia-kernel-module , reinstall the package "nvidia-glx" again, as there have to be set some symlinks and rights.

Pay attention, that all users, which shall use acceleration are in the group "video". By default they are not in Debian ! It is one of the most errors.

Hint: Just move "gdm" out of the way from /etc/init.d/ so it will no more start after reboot. O.k., if you have done this and got a shell after reboot, you can easily test with the command "startx" as root. Now you an see, what happens.

If everything works fine, move gdm back to /etc/init.d/

If everything works, and ist starts fine, you can test acceleration with "glxgears -printfps" in a shell of a KDE or similar. You should have about 900-1300 FPS for your card.

As far as I know, acceleration needs some additionally Debian-packages, mesa-glx as I remember, and some more. Debian should know this.

O.k., what can I tell more ? I think, you should test it for now, if it wil not work, just write me again.
Good luck !!


OK, I have done the following:
1) disable glx and run nvidia driver - still crashes
2) load nv driver - crashes, but not immediately upon login - alsaconf always causes a crash
3) disable glx and load nv driver - same results
4) give up and run vesa driver - solid - no crashes - can't run flightgear
5) have previously run both Knoppix and Ubuntu live CDs - both crash

Since the card works with vesa driver, just no glx and hardware accel,
I have to assume my computer board and memory are OK.  I have run
memtest extensively.

I have always intended to purchase a better graphics board once I get
the system running will.  I'd like to solve this problem first.

Any further suggestions gratefully accepted.
