Hello!

Yesterday i tried to use nvidia driver version 515 with my M1200M,
but got an error in the Xorg.0.log:

i do not find glxserver_nvidia in the running version 470:

Does anyone has a hint on how to solve this?
There is no '*glxserver_nvidia*' file in the Solaris driver distribution
https://us.download.nvidia.com/solaris/515.76/NVIDIA-Solaris-x86-515.76.run
so I'm not sure why they expect such file (module) to exist.  Maybe this
is a bug in their package?  Either they forgot to add the module into
the package, or they mistakenly require it when they shouldn't?  Maybe
you could try to contact NVIDIA.


Regards.

Hello!

Looking a bit around i think its the GLX module that is not "NVIDIA"

[   234.053] (II) LoadModule: "glx"
[   234.055] (II) Loading /usr/lib/xorg/modules/extensions/amd64/libglx.so
[   234.071] (II) Module glx: vendor="X.Org Foundation"
[   234.071]     compiled for 1.19.7, module version = 1.0.0
[   234.071]     ABI class: X.Org Server Extension, version 10.0

and the glxserver is a method within that or something similar..
...
# nm -D
NVDAgraphics/reloc/X11/lib/modules/extensions/NVIDIA/amd64/libglx.so.1|fgrep
-i glx

[6]     |            14550384|                  24|OBJT |GLOB |0    |22
|glxserver_nvidiaModuleData

That entrypoint is not present in , e.g., 295.40 . So probably a
packaging error by NVIDIA.
I thought initially the same, but:

$ /usr/bin/nm -D nvidia-470/NVIDIA-Solaris-x86-470.141.03/NVDAgraphics/reloc/X11/lib/modules/extensions/NVIDIA/amd64/libglx.so.1|fgrep -i glx

$

and 470.141.03 seems to work okay (at least this is my understanding from OP).


470 works. From the running machine with 470 i follow the GLX module from Xorg.0.log like this:

$ grep -i glx /var/log/Xorg.0.log

Where does the link in /var/run come from ?


from /lib/svc/method/ogl-select that calls
/lib/opengl/ogl_select/nvidia_vendor_select
