I am attempting to run an opengl application remptely to a ubuntu
linux machine from my windows 8 machine.
To do so I start the cygwin console, call startxwin.
Running glxinfo | grep OpenGL returns the vendor of my graphics card, NVIDIA.
glxinfo |grep OpenGL
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 580/PCIe/SSE2
OpenGL version string: 1.4 (4.4.0)
OpenGL extensions:
Then I ssh on the ubuntu machine using -X -C as the parameters.
When attempting to start the application the console reads
extension "NV-GLX" missing on display "localhost:10.0".
Afterwards, the cygwin/X server crashes and I have to restart it.I
attached the log from
/var/log/Xwin/XWin.0.log
Thanks for the bug report.
I'm afraid that the log doesn't contain enough information for me to
identify the cause of the crash.
Can you install the xorg-server-debuginfo package and try again?
I also have been working on a tool to automate sending better crash
information using minidumps. If you would like to try that, download it
from [1] (anonymous ftp) and put it into /usr/bin and reproduce your
crash again.

Does cygwin/x support running OpenGL applications remotely? Am I
missing something? Do I have to install the mesa-utils libraries on
the remote machine?
Yes, this should work.
I'm not entirely clear if the 'extension “NV-GLX” missing' message is a
warning or an error, but according to the internet it seems to be due to
having a Nvidia libGL installed on the remote machine, so if all else
fails you might look at uninstalling the Nvidia proprietary driver and
libGL, and using mesa instead.
