I'm running Ubuntu 16.04LTS guest on a Windows 10 host. The guest additions appear to be working since Ubuntu is able to run at full resolution, clipboard sharing works, etc. However, 3d acceleration will not work, causing Unity animations, etc. to run VERY slowly. Typing
sudo /usr/lib/nux/unity_support_test -p gives the following result:
OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits) OpenGL version string: 3.0 Mesa 11.2.0 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no
Yet, checking Software&Updates in Ubuntu shows that the proper VBox drivers are actually being used:
So I'm not sure why I'm not able to benefit from 3d acceleration.
