Most Nvidia Linux users get an exploded view of the desktop after installing the Nvidia drivers.
The procedure below is applicable only if you have successfully installed the Nvidia drivers for your linux operating system.
You do not need to install third party drivers from different repositories anymore if you have successfully/correctly installed the drivers.

1>Once the driver is installed reboot the system.

2>Find out what are your Monitor specifications: specifically the horizontal and vertical refresh rate.

3>The horizontal and vertical refresh rate will be given in your monitor/TV manual. Or else go to your vendors site and check
the specifications for your particular model and zero in on the refresh rates. That is the only thing you need. Im using a Samsung SyncMaster 920NW from 2007, so i looked it up and found my horizontal rate @ 30 - 81 and vertical rate @ 56 - 75.
Once you have your particular model's refresh rates, go to your xorg.conf file and enter the values there.

2>Open your xorg.conf file in the text editor of your choice( i use nano).
On ubuntu based systems xorg.conf is located in /etc/X11/xorg.conf.

So i do this after i open terminal and go root:
Code: Select all
sudo nano /etc/X11/xorg.conf


Once the file is opened up scroll down to Section "Monitor".
From the above image the highlighted 2 lines is where i enter my horizontal and vertical refresh rates. Enter your values here.

Once you enter your respective values -- save and exit. Next logout and login and check nvidia-settings. You will see a wide range
of resolutions your monitor supports. If you cant see it then reboot and check again. Open nvidia-settings as root and apply the reslolution you want so that it will stick across reboots..

To add to Pam's post. To open nvidia-settings as root you will need gksudo. This program is like sudo but is designed for graphical programs. So to install it:
Code: Select all
sudo apt-get install gksu
*Yes gksu

Now, to open nvidia-settings:
Code: Select all
gksudo nvidia-settings

This should open a password prompt. Enter your password and you are running nvidia-settings as root. :)
