My game doesn't work on Linux

My game works fine on windows, I made Linux build
Testing on Ubuntu in VirtualBox, the resolution screen display, I choose resolution and launch, but the game doesn’t run after that.

When I launch from console :

joel@joel-VB-Linux:~/Bureau/Fight-for-Galaxy$ ./'Fight for Galaxy.x86_64'Set current directory to /home/joel/Bureau/Fight-for-Galaxy
Found path: /home/joel/Bureau/Fight-for-Galaxy/Fight for Galaxy.x86_64
Mono path[0] = '/home/joel/Bureau/Fight-for-Galaxy/Fight for Galaxy_Data/Managed'
Mono path[1] = '/home/joel/Bureau/Fight-for-Galaxy/Fight for Galaxy_Data/Mono'
Mono config path = '/home/joel/Bureau/Fight-for-Galaxy/Fight for Galaxy_Data/Mono/etc'
displaymanager : xrandr version warning. 1.4

Using libudev for joystick management

Importing game controller configs

Scripts are in C# language, and I use Unity Version 5.3.1f1 Personal Edition
I watched similar questions here but finded no solutions

Ok, I managed to make it run from console:

javier@ubuntu:XXX$ ./YourGame -force-opengl

Adding “-force-opengl” at the end.
I’m using ubuntu 14.04 LTS in a virtual machine on VMWareWorkstation, and Unity 5.3.5f1.
