Hi Aquarius, looks like you got into trouble with nvidia-driver. You should uninstall these, then doing a dist-upgrade and then conetrate to install the nvidia-driver again.
I prefer two possible ways to uninstall all nvidia-packages (but check before telling "y"): apt-get --purge remove nvidia-* or aptitude purge ~nnvidia-* Both should work. But as I said, look, what is going to deinstalled, before telling YES. In most cases these commands are working well. When they are all deinstalled, reinstall the required package. Note: You must have a graphics card with Geforce 9 or higher! Otherwise the package will not be installed. Check your hardware if it is supported by the package. Note, you must have kernel-headers installed. Good luck!
