x.plot crashes with OpenGL2 error (X server in XDMCP mode) #393

jypeter · 2019-03-13T16:46:01Z

@doutriaux1 First test of vcs in 8.1 and I get a crash

My setup

Windows 7 machine, running VcXsrv X server in XDMCP mode

I have unselected "Native opengl" because otherwise my X server crashes if I try to execute "glxgears" (event with LIBGL_ALWAYS_INDIRECT=1)

glxinfo in a terminal on my server (when running VcXsrv+XDMCP) gives me the following output

Now, from the same VcXsrv+XDMCP, if I ssh to a remote server where I have also installed CDAT 8.1, I get a slightly different error

glxinfo gives me the following output

And when I run the same vcs test as above, I end up with a LOT of error output (I have just pasted part of the end below, anyway I can't scroll to the beginning, there is too much output), and a blank/empty canvas. I'm back at the python prompt, no crash like the previous test

@scottwittenburg @danlipsa looks like yet another case of older X server. @jypeter I think the switch to OenGL2 essentially made it incompatible with older X server... I think you will have to use the mesalib version here and ask users to first dump to a png. Other options are to upgrade your X server. Is that correct @danlipsa @scottwittenburg

danlipsa · 2019-03-13T18:43:51Z

The Mesa library seems new enough but for some reason it does not provide OpenGL 3.2 which is needed for this version of VTK. One path to address this kind of problems in the future is to ship our own mesalib even with the on-screen version of vcs and use an option to switch between using the system driver (which in this case does not work) and using the mesa OpenGL that we ship with our software. ParaView already does this. See options at the end of the following blog:

https://blog.kitware.com/messing-with-mesa-for-paraview-5-0vtk-7-0/

danlipsa · 2019-03-13T18:45:17Z

@doutriaux1 Indeed for now the workaround is to use the offscreen version of vcs.
