Blender doesn't open/run? How do I fix this?

Question

I used sudo apt-get install blender to install blender on Ubuntu 9.10

But it doesn't open. When I click
Applications > Graphics > Blender (fullscreen)
or
Applications > Graphics > Blender (windowed)
nothing happens.

Your Ubuntu seems to miss accelerated 3D graphics. You need to install a decent video driver; see System -> Administration -> Hardware Drivers if it suggests something for you already.
