The 3D cannot be easily enabled. A thread that people refer to is
but I tried several suggestions on that thread and it doesn't work yet.
The message is:
No Python OpenGL support
No Python GTKGLExt support
However I think 3D mode is ugly as well.
Mine worked with just installing the 2 commands, I believe if that does not work it must be your video card. I have to agree the models in 3D look uglier than 2d. I think someone could have spent a little more time in the decoration department. :P
