Test For Unity Graphics Support
Unity 2-D or Unity 3-D? Fear, uncertainty and doubt prevail, as more users wonder if the Unity desktop is dramatically raising the minimum graphics hardware requirements.
The honest answer from Canonical is no, Unity tries to take advantage of features that have been specified or released many years ago. What they can't tell you is how many of those supported features you have in your ancient box under your desk.
Canonical has tested Unity on a variety of legacy hardware to identify the minimum specs required for Unity, making reasonable assumptions that newer hardware from AMD, Intel and NVidia will be more capable than the ones in the test rig. Tests are aimed at establishing system stability, as well as responsiveness and graphics rendering performance.
There is a standard test that you can run on any bit of kit - even running a Ubuntu Live CD, so you don't have to install first). In a terminal - yes, it's a good ol' command line utility - run:
/usr/lib/nux/unity_support_test -p
Here's what I get on my trusty Nvidia Go7300 mobile card:
robin@d6400:~$ /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce Go 7300/PCI/SSE2 OpenGL version string: 2.1.2 NVIDIA 280.13 Not software rendered: yes Not blacklisted: no 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
Looks like it's Unity 2-D for me!
The differences between Unity 2-D and Unity 3-D are almost entirely aesthetic. Unity 2-D disables 3-D effects, shadows, window-snapping and some of the fancy animations effects of Unity 3-D.
The core functions and components of the desktop environment remain the same.
