[Gmsh] Gmsh doesn't run

[Martin Vymazal]

Hello Matti, hello Christophe,

  I can run gmsh now. Thank you for the fix.

  However, gmsh is still unusable for me as I don't see any mesh after  
meshing (doesn't matter if it's 2D or 3D). The behaviour is following:

Tools->Options->Geometry->Visibility->[Points | Lines | Surfaces |  
Volumes] - everything works fine.

Then I mesh and I still see my geometry, but no mesh.

Tools->Options->Mesh->Visibility-> Nodes ... works fine
                                 -> Lines ... I see some more nodes,  
but no lines
                                 -> Surface edges ... even more nodes, no lines
                                 -> Volume edges ... has no effect
                                 -> Volume faces ... has no effect

I also tried to mesh in command line (gmsh -3 myfile.geo) and open  
myfile.msh with gmsh. All I get is an empty window.

Playing with mesh visibility options, I see a lot of error output in  
the terminal from which I run gmsh. The messages usually say something  
like:

XRequest.135: BadLength (poly request too large or internal Xlib  
length error) 0x2
XRequest.135: GLXBadLargeRequest 0x2
XRequest.135: BadLength (poly request too large or internal Xlib  
length error) 0x3800013
XRequest.135: GLXBadLargeRequest 0x2
XRequest.135: BadLength (poly request too large or internal Xlib  
length error) 0x2
XRequest.135: GLXBadLargeRequest 0x2
XRequest.135: BadLength (poly request too large or internal Xlib  
length error) 0x2


In the end, the only thing I have left from the mesh is a bunch of  
nodes. I have this problem in my laptop with Nvidia Quadro FX 570M and  
binary nvidia drivers version 190.42-1. I have no problem with gmsh  
and intel graphics card (different computer, the same linux  
distribution, identical system settings). Therefore I suspect this to  
be a graphics-related issue.

Does anyone have a similar problem?


Best regards,

    Martin Vymazal
