" After installing Ubuntu 18.04 using the "erase and install" option Ubuntu logo screen came up with red to white dots.
After white dots went red, screen froze, then screen went black "
Usually this problem occur if Ubuntu does not recognize your computer.
It might have happened because you deleted your surname from computer name field doing the installation.
To fix this problem we need to reinstall Ubuntu and choose a different user name:
1. Make sure you are connected to the internet.
2. Reload the installation
3. Choose the erase and install option.
4. Choose a new name, computer name and user name.
