Yesterday i've installed ubuntu 11.04 (instead of 10.10). And i need to install nvidia driver which supports opengl 3.3 In 10.10 i did it in a such way:

Ctrl+alt+f1 login

sudo /etc/init.d/gdm stop
sudo sh driver.run 
startx

Not it doesn't work. Because ctrl+alt+f1 doesn't show login screen. Just only black screen. I've googled this problem. Some people have it but no one knows how to solve. Sometimes people say that it is connected with video card or driver. But i have GeForce 9300M G, and i've activated a standard driver. Anyway, it worked in 10.10, but doesn't work now.

The main problem is that i need to kill xserver to install this driver. killing the process just only restarts xserver.

Also, I've tried to /etc/init.d/gdm stop in GUI-console. It says that "Fake initctl,doing nothing". Google didn't helped in this case too.

Any ideas to install that driver?
