I am a new user to GMSH. 
I downloaded the current stable release (version 2.13.2) 64 bit Linux version of GMSH, last week, from the gmsh website (http://gmsh.info/). 
When I checked the About Gmsh option in Help menu, I found it says Version 2.8.3 . The file I downloaded from the website is named " gmsh-2.13.2-Linux64.tgz ". 
Because of this I am not sure if I am using the latest version 2.13.2 . 

The problems I face : 

1.) As soon as I launch gmsh from the command prompt I find these two lines, always..... 

libGL error: failed to open drm device: Permission denied 
libGL error: failed to load driver: i965 

My system is Linux 3.13.0-77 (Ubuntu version 14.04. 4LTS) 

2) gmsh window hangs too much, when I go for generating the mesh (2D or 3D) even with simple cube of 3 nodes per line. 
3) Sometimes, When I change the number of nodes on lines in my script and then Reload and try to mesh with 3D from GUI window of gmsh, the window CRASHES abruptly. 
4) I see the error messages : 

gmsh: ../../src/XlibInt.c:245: _XPrivSyncFunction: Assertion `dpy->synchandler == _XPrivSyncFunction' failed. 

[h2-efd-seth:03831] *** Process received signal ***

Could someone help me with this, please ? 

Many Thanks,
