another thread about 3d Hardware acceleration wih NVIDIA
 

Trying to activate 3d hardware acceleration
NVIDIA GeForce2 GPU driver
I have downloaded & installed the nvidia drivers (through suse's update service)
3d graphic acceleration enabled, but when trying to play tux racer "3d hardware support not enabled"
have looked in suse database (which suggests the below actions) & have read the readme file.
However have not got it working!!
please could someone help

thanks

:newbie:

And in your XF86Config file you have the option

Load GLX

and not..

Load DRI

sorry, please could you explain what i need to do?
are you saying I should I type something like:

linux:/home/le # /usr/X11R6/bin/load glx

???

xf86config
 

To find more info regarding the XF86 config file, i went straight to the "horse's mouth", and got the insturctions form NVIDIA:

nvidia link

i went into /etc/X11/XF86Config (opened it up in a text editor), and followed nvidia's instructions on it (section 3).

Done it twice so far, and this worked for me. Only bad thing: you have to do it over with upgrading your kernel.

HTH,

dan

thanks, have looked at the readme file & my xf86 config
it appears I don't have glx.
this is part of the output:

II) LoadModule: "glx"
(WW) Warning, couldn't open module glx
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (module does not exist, 0)
(II) LoadModule: "nvidia"
(II) Loading /usr/X11R6/lib/modules/drivers/nvidia_drv.o
(II) Module nvidia: vendor="NVIDIA Corporation"
compiled for 4.0.2, module version = 1.0.4496
Module class: XFree86 Video Driver

and

EE) NVIDIA(0): Failed to load GLX
(II) NVIDIA(0): Using the NVIDIA 2D acceleration architecture

what next?? should I try and re-install the nVIDIA drivers??



:newbie:

I would get the latest drivers from the nVidia site and follow them to the 'T' - my installation went fine - the instructions were very informative and I was really pleased overall. worked like a charm IF you follow the instructions properly.

OR - just go over their instructions anyway and see if their instructions for the file editing can help you - they should be pretty similiar.

When you try to run glxgears as root from a user account you'll need to do xhost + first as the user to allow root to use the x server.

why does glx not load / exist?

You'll probably better off to get the drivers from nvidia and install those instead of the Suse setup.Something seems to go wrong there.You can also try this to see what goes on there:

thank you, I really appreciate your help
it appears that the newest drivers are installed
as you can probably tell I'm pretty new to this!!

Check with /usr/X11R6/lib/modules/extensions
There should be a link called libglx.so to /usr/lib/opengl/nvidia/extensions/libglx.so
At least thats what it loads for glx here.

/usr/X11R6/lib/modules/extensions

is empty

You could try to add this link if the lib exsists in /usr/lib/opengl/nvidia/extensions/libglx.so
As root do:
cd /usr/X11R6/lib/modules/extensions
ln -s /usr/lib/opengl/nvidia/extensions/libglx.so

If that doesn't work get rid of the link afterwards.

thanks
have done above
lib glx.so is now there along with other stuff
I have rebooted
but still get following in my xf86 log & no 3d hardware acceleration.

should I get rid of the link, and if so how? (can I just delete them all in file manager)

II) LoadModule: "glx"
(WW) Warning, couldn't open module glx
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (module does not exist, 0)

You can delete the link in a file manager - no problem.
I'd try to uninstall the Suse-nvidia stuff you got in there and install the drivers from nvidia's website.
