How did you compile mesa and what settings did you set in CMake to enable osmesa for ParaView? I don't believe there should be X11 classes in your stack trace if it is configured to do off screen rendering. For example, here is how Kevin Hobes builds mesa and configures ParaView on his RedHat cluster.<div>

I have a few issues with getting paraview v3.10.0/v3.10.1 running without getting a segmentation fault just after the logo window appears and the Qt window builds up. This happens only for the time being if I am using the following settings:<br>
+ MPI support enabled (using openMPI v1.4.3)<br>
+ OS MESA enabled (v7.9.2), using MESA for all openGL includes and libraries.<br>
+ QT v4.6.3<br>
+ Python 2.7.1<br>
+ CMake 2.8.4<br>
<br>
The system is Linux x86_64 based on SLES10.<br>
<br>
The segmentation fault does not appear if I leave OpenMPI out of the loop (ie building without MPI support). Using the standard OpenGL libraries (disabling full CPU rendering and using GPU rendering instead, i.e. VTK_HAS_OSMESA=OFF) and MPI support does not produce the segmentation fault either.<br>
<br>
I have been backing off the CMAKE_BUILD_TYPE=Release and switched to CMAKE_BUILD_TYPE=Debug, the recompiled paraview from scratch, alas without any success. I still get the same segmentation fault. I have tried also with the system compiler (gcc 4.1.2) and newer compiler versions (gcc v4.5.1 and 4.6.0), the result still being the same.<br>
<br>
I have included a backtrace from gdb in order to check where the segmentation fault is produced and it looks like this happens in vtkOpenGLRenderWindow.cxx on line 241.<br>

I have been successfully compiling and installing on the same computer paraview 3.8.1 without any issues, using similar settings:<br>
+ QT v4.6.2<br>
+ Python v2.7<br>
+ MESA 7.7.1<br>
+ openMPI 1.4.3<br>
<br>
The software rendering is working like a charm and the reason why looking forward to using paraview 3.10.X is the enhanced support for parallel rendering. I am quite sure I am doing everything right but it would be great to know if someone would be pointing me towards a fix for this issue.<br>
<br>
For information, I am using a compute cluster which does not have dedicated GPU hardware and, mainly for this reason, I am relying heavily on CPU based, parallel rendering for performing postprocessing. Paraview v3.8.1 has been running on this cluster for the last 4 months now without given any trouble.<br>
