Install the NVIDIA graphics card driver in Ubuntu

First confirm that the software source has been selected (the method will not be described here)
Enter
 

 Sudo apt-Get install build-essential
After the installation is completed, press enter to complete the preparation.

Press CTRL + ALT + F1 and convert it to the text interface. After logging on, enter
    Sudo/etc/init. d/gestation stop
For KDE Desktop, enter
    Sudo/etc/init. d/KDM stop
Enter
    Sudo SH (path and file name) (save in the main folder as an example sudo sh dis. Run)
So the installation interface appears ......

After installing the program, enter

    Sudo/etc/init. d/gdmstart                 -- GNOME Desktop

 Or sudo/etc/init. d/kdmstop                  -- KDE Desktop

But don't be too happy, because you may find that the title bar may disappear.

1. First, disable the special effects of ubuntu (I will not go into details here)

2. Open the terminal and enter

   Sudo NVIDIA-xconfig -- add-argb-Glx-metrics als

3. Disable interruption, log out, and log on again

4. After logging on, you can re-enable the special effect.
