[HELP]I'm having a problem with play test in 2D

I’m a beginner in this interface and I am having a problem with my Unity3d. When I’m making a 3d game, my Scene show me the camera and my character, but when I change to 2d becomes black or the same occur when I click in Play to test . Anybody knows what I can to do to fix this? (I’m using the Unity3d in Linux Mint to make my game).

Thanks

Where is the camera in relation to your character? Is the character in the field of view? Also, do you have a light in your scene?

Yes, I have a light in my scene and my camera is on the character. I think that the problem is with the configurate of the OpenGL, because in the name bar on the top, there are an information that is deprecated, and I installed the Unity in my windows part and there worked fine.
