As the title says I can't enable the Unity 3D support when I'm using open-source drivers (xorg-edgers). I have an xfx Radeon HD 6950 by the way.
If I install the proprietary 12.3 drivers from AMD it works, but I get poorer 2D performance than the open-source drivers and also I get some freezes and lock ups at random. So because of this I'm trying the open-source drivers and so far no issues at all, except this one.
Running this command $ /usr/lib/nux/unity_support_test -p
shows this:
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x300)
OpenGL version string: 2.1 Mesa 8.0.2
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
And this command $ lspci -nn | grep VGA
shows:
01:00.0 VGA compatible controller [0300]: Advanced Micro Devices [AMD] nee ATI Cayman PRO [Radeon HD 6950] [1002:6719]
So, is this normal? Do I need to go back to proprietary drivers to enable Unity 3D?
If anyone can give me help, I'll much appreciate it.

I was having same problem with an integrated Radeon 4250 (RS880) and solved it after installing also the xserver-xorg-video-ati package.
I read in the info about the package that:
"Users of Rage, Mach, or Radeon boards may remove this package only if they use Driver "r128", "mach64", or "radeon" in /etc/X11/xorg.conf instead of relying on autodetection."
So it seems I was using autodetection.
Now I get 3D acceleration (and Unity 3D) although I noticed the mouse cursor is not smooth at the login screen (it freezes for a fraction of a second each one second).
