Comment 6 for bug 1283558

Hi,

based on your output of glxinfo

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)

You don't have any OpenGL-capable graphic card driver installed at all.

Some other programs (I assume this includes Minecraft) have less strict requirement, and probably also work with software rendering, but Unity3D really needs a correct graphic card driver. Nevertheless I cannot really imagine that Minecraft runs smooth when it only uses software rendering, so I'm really wondering why you didn't notice this problem earlier. ;-)

As a first step I would suggest you to check which graphic card you're using exactly. You can use the following commandline to do this:

lspci | grep VGA

I assume its an Intel graphic card, at least the following line sounds like it is one:
libGL error: failed to load driver: i965

To install the Intel driver you could for example use (as mentioned in Michaels link above):

sudo apt-get update
apt-get install libgl1-mesa-dri:i386 libgl1-mesa-dri

Hope this helps to solve the problem ;-)
