When I open "details" at dash home, I check what graphic driver my computer is using but it says unknown. Is this a bug or anything else? What should I do? I'am using ubuntu 12.04

Installing mesa utils should take care of that. In a terminal, run the following command:

sudo apt-get install mesa-utils

It is not missing if you have anything other than a text only screen, it is a harmless to leave it like that, your system has found it but the "details" windows does not find it.
You can verify it by typing into a terminal:

lspci | less

the second entry will be your graphic card.

If you want to have it identified you can install mesa-utils with

sudo apt-get install mesa-utils

mesa-utils will also give you some diagnostic programs to check that your 3D render is working properly such as: glxdemo, glxgears, glxheads, glxinfo
