Comment 11 for bug 1049067

I am new to using Ubuntu 12.04 and Linux. My Unity "Appearance" does not show the Icon size so that I can adjust it smaller. I found some reference to 3d acceleration no working and issued a suggested command

/usr/lib/nux/unity_support_test -p
Result:
OpenGL Warning: Failed to connect to host. Make sure 3D acceleration is enabled for this VM.
libGL error: failed to load driver: vboxvideo
libGL error: Try again with LIBGL_DEBUG=verbose for more details.
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 9.0.3
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

So then I tried to read up on VirtualBox support of graphics acceleration, and found my way here.
I do use the most recent version of VirtualBox on a Windows7x64bit host Dell IXPS 15 Laptop with NVIDIA GeForce GT540M 2GB graphics with optimus and an Integrated Intel Graphics Card. I am running it with the NVIDIA card enabled.

I would like to be able to reduce the size of Unity Icons, however I'd also like to know that the programs I am running are using acceleration.
