Ubuntu 640x480 issue

In ubuntu, if you have only one monitor resolution of 640x480 and you are unable to find any other resolutions in the display resolution settings even if you have updated the NVIDIA drivers, kindly follow the below procedure to get back your original resolution (1366x768 for my Lenovo Laptop).

Step1: Open Terminal (Ctrl+Alt+T).

Step2: Type the below command and hit Enter and then Enter the system password.
            
      $ sudo gedit /etc/X11/xorg.conf

Step3: The xorg.conf file gets opened. Then change the below lines
            
             HorizSync 28.0 - 33.0
      VertRefresh 43.0 - 72.0


             to

            HorizSync 30.0 - 83.0
     VertRefresh 56.0 - 75.0

Step4: Save the file and exit. Then, restart the system. This should fix the issue.
