It was problem with Nvidia driver. I just switched to opensource default driver and now is working.

another solution is to compile the osmesa version (just look inside the CMake) which is great as it does not require any GPU. The problem is that if your version is too old, results can be crappy (the quality of OSMesa varies over time).
