Install Nvidia Driver on Ubuntu Box

I noticed that Xorg process is taking too much of the CPU in my UBuntu box. I suspect that the video driver for my Nvidia graphy card may be not good. So I started to try other versions of drivers in hope to find a better one.

# obtain graphy card information
lspci | grep -i vga
03:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 295] (rev a1)
04:00.0 VGA compatible controller: NVIDIA Corporation G98 [Quadro NVS 295] (rev a1)

Before installing I add the X Ubuntu Updates team PPA repository

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update

1. Removing all the old Nvidia drivers

sudo apt-get --purge remove nvidia-*

2. Install the nvidia drivers.

# verify which nvidia package are available
apt-cache search nvidia | sort
sudo apt-get install nvidia-current-updates
# After installation run the following command to initiate the configuration:
sudo nvidia-xconfig
sudo reboot
