NV-GLX missing extension in OS X Lion

I connect to a remote linux machine using "ssh -X machine", and then I run a graphical application, so its window is displayed on my local OS X Lion machine using X Window. I get the error

"Xlib: extension "NV-GLX" missing on display "localhost:11.0"."

The application moves very slow. Is it any way to use NV-GLX on OS X or to cimcurvent this problem?

I've encountered similar problem trying to connect from a laptop with AMD graphical card to a linux server with NVIDIA card and drivers installed.

If you have root access to your remote linux machine you could try to restart X server with default libglx.so, not the one from NVIDIA driver package. Appears that NVIDIA installer doesn't support partial installation (only driver, no GLX lib), so one needs to remove NVIDIA libglx.so from xorg modules path, but leave nvidia_drv.so. On Debian you could do

# update-alternatives --config glx # select mesa-diverted
# ln -s /usr/lib/nvidia/current/nvidia_drv.so /usr/lib/xorg/modules/drivers/

Be shure your remote /etc/Xorg.0.log has following parts

...
[  1111.390] (II) LoadModule: "glx"
[  1111.390] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so
[  1111.390] (II) Module glx: vendor="X.Org Foundation"
...
[  1111.391] (II) LoadModule: "nvidia"
[  1111.391] (II) Loading /usr/lib/xorg/modules/drivers/nvidia_drv.so
[  1111.392] (II) Module nvidia: vendor="NVIDIA Corporation"
...

After that Xlib: extension "NV-GLX" missing on display "localhost:11.0" message should go away
