Dear VMD list,

I think that this question was asked previously. I wonder whether anybody
has had the same problem and found a solution.

I am trying to open VMD remotely. The server where VMD is started from has
an ATI video card with the fglrx driver, while the client where VMD should
appear has NVIDIA with the proprietary driver. VMD crashes with
"segmentation fault". Also, "glxgears" and "glxinfo" crash with
"segmentation fault". Everything runs fine though locally on both
desktops.

I found that setting the following variable can help improve things:

setenv LIBGL_ALWAYS_INDIRECT y

After setting that, glxgears works and VMD can be started. However, as
soon as I try loading a molecule into VMD the entire Xorg on the client
crashes. Has anybody had the same problem and found a solution?

Interestingly, everything works fine if I open VMD remotely from a server
that has NVIDIA to a client with NVIDIA.

Would it help to compile VMD against mesaGL if this problem is related to
openGL?

Thanks,

      Gianluca
