Simulate non-existing 3D Driver

I'm currently developing a 3D-based Application (In C++, if that matters). To test special circumstances, I also need to test the behaviour when no 3D Interface coul开发者_如何学编程d be loaded (e.g, glutInit() failed).

The environment is currently Linux, so a Linux-based solution would be preferable.

How would I test a case where no 3D Interface could be created, without unloading the binary 3D driver from my kernel (which is nVidia)?

Try running the application under something like a VNC server, or Xnest. Those don't generally support OpenGL.

Run it under a virtual machine using VMware or VirtualBox.
