With a brand new install of 12.04 on my Dell Inspiron M5030, Unity 3D appears to load everything but the icons in the top left, and I am unable to click on anything. Unity 2D seems to works fine however.
I have done nothing except install Synaptic Package manager and follow this guide to install FGLRX Drivers under Settings ? Additional Drivers, the driver shows as installed and functioning.
Also after running: /usr/lib/nux/unity_support_test -p, I get this:
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Mobility Radeon HD 4200 Series
OpenGL version string: 3.3.11653 Compatibility Profile Context
Not software rendered: yes
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: yes
I am unsure as to what the problem is. I have tried the non-proprietary drivers, I could not get them to work either, but I would be willing to try again.
