nVidia drivers problem, black screen after installation

Hello,

I installed Ubuntu 9.04 today, it is now up to date. Everything goes good till i want to install/activate nVidia graphic drivers. Im doing this with "Hardware controllers" clicking "Activate" button at nVidia 180 (recommended) then, i have to reboot.

After loading screen the problem shows up: Black screen where login screen is supposed to be, thats all. Cannot use keyboard to change to console, nothing.

The only way to get in is with recovery mode with the option xfix.

Im using nVidia 6200.

xorg.conf made while installing nvidia:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
