Visually testing on Ubuntu Server?

I've purchased an OpenVS VPS. The currently installed OS is Ubuntu Server 14.04 LTS, and I've successfully compiled and run both the MasterServer and Facilitator on it. But now, I'm trying to find a way to get visual server-side feedback (temporarily, for debugging purposes). I've successfully installed Ubuntu-Desktop, vncserver & WINE, but the Unity 3D test server app seems to crash in it at startup. I assume this is because there is no hardware acceleration, since this is all done through virtualization in a VNC viewer, so there's no direct access to an actual, physical graphics card...

So, that being said... Is there any way to get this to run in software rasterization mode? I'll be happy with native OpenGL, or a virtual Direct3D, as long as it actually runs outside of headless mode. What can I do to make this happen?
