gallium llvmpipe in Ubuntu 13.04

Hello everyone, please help me. I'm not a programmer, designer, just 
user of Linux OS, but I want to make its graphic system better. How can 
I set gallium llvmpipe driver in it. I try to use Ubuntu 13.04.

I used to Debian before

glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on ATI RV350
GL_EXT_vertex_array_bgra, GL_NV_conditional_render,

glxgears

301 frames in 5.0 seconds = 60.025 FPS

But in this configuration the FPS more twice.

glxinfo |grep render
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x209)
GL_NV_conditional_render, GL_AMD_draw_buffers_blend,

glxgears

640 frames in 5.0 seconds = 127.836 FPS

But unfortunately in Ubuntu 13.04 I can't do the same:

Only so:
