I'm not 100% sure, but I believe nvidia-settings will display an error if the 3D drivers are not installed properly.

I am not a technician and I have some problem in understanding your conversation. These are the results of both the tests you argued:
[root@ESPERYDES:/home/djangou# glxinfo | grep -i direct
direct rendering: Yes
GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access,

root@ESPERYDES:/home/djangou# glxinfo | grep -i render
direct rendering: Yes
OpenGL renderer string: GeForce GTX 260/PCI/SSE2
GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image,
GL_NVX_conditional_render, GL_NVX_gpu_memory_info,
]
Can I suppose my video card is well configured? If not, what kind of tests can I do?
I thought too that at reboot and choosing Ubuntu, no splash animation appairs and I go directly to the desktop. Maybe this symptom depends on another problem, anyway I report this stange bug. A bad installation of nvidia drivers can cause this problems?
Thanks to all of you.

Yes, it does look like your nvidia driver is installed properly and enabled:

Sure, you are good to go with compiz.
Note: I have never actually used compiz myself, since I always prefer a light and fast desktop over fancy 3D eye candy any day. So I may not be able to provide much help with compiz stuff.
Here are a couple of good tutorials on compiz though:
For installing compiz:

https://help.ubuntu.com/community/Co...r/CompizFusion
And for configuring compiz:
https://help.ubuntu.com/community/Co...figuringCompiz
Write back if you need more help. Although I have no direct experience with compiz, I will try to answer any questions I can about it.

Taking into account the info that Adam reminded me of (and I will try to actually remember it this time!) I have highlighted in bold the important output from your: "glxinfo | grep -i render"
The fact that it says "direct rendering: Yes" along with the OpenGL render string line that lists your card:
"OpenGL renderer string: GeForce GTX 260/PCI/SSE2" instead of saying software, means you are good to go nvidia wise. At least, that is how I understand it anyway. I am far from being a technician myself you know. I'm just a regular end-user guy who tries to learn as much as I can about this stuff, and pass the knowledge on when I can.

EDIT: Also run nvidia-settings in the terminal. Highlight the OpenGL/GLX Information section on the left pane. On the right pane it should say: direct rendering: yes, and list all the GLX extensions and stuff.

Yes, that is all correct, and compiz should run just fine. You are not likely to get a fancy slash screen during boot up as that only works with a high resolution console framebuffer, which the nvidia driver does not support.

And, finally, you really should not be running things as root (as you did with glxinfo) unless it's for system maintenance.

OK, thanks for that Adam. That is indeed what I thought.

Good eyes! I did not even notice that.
Yes indeed, you should not ever be logging in and running the system as root. I hope you are not doing that.
Using a root terminal in linux is fine for system maintenance as Adam said, although it is not necessary in this case.

NOTE: Enabling the root account is not recommended in Ubuntu. I have always used sudo on Ubuntu and I have never had a problem with it.
