Well, the Nvidia driver that ships
with Ubuntu 10.10 only gave me an ever
lasting purple screen, so I decided to
try the manufacturer driver directly
and it worked perfectly! It was
actually pretty simple: go to
http://www.nvidia.com/Download/index.aspx?lang=en-us
and select your graphics card model. I
have a Sony Vaio VPCF1, so I chose
Product Type: GeForce Product Series:
GeForce 400M Series Product: GeForce
GT 425M Operating System: Linux 32
bits Language: English (US)
Download and save the 260.19.29 driver
installation script anywhere you find
convenient. Then, make it executable
sudo chmod ugo+x
Reboot the computer, choose Ubuntu
Safe Mode and boot into root shell.
Then, change the runlevel
telinit 3
Run the installation script and follow
the instructions on screen. That's all
you need.
