   Save the file and exit the vi editor, then execute the following command to update Grub:

   sudo update-grub

   Finally, restart the computer.

4. Other Possible Problems

   If none of the above solutions work, then other problems may be causing the black screen. This may include hardware failures, software conflicts, etc. This requires further debugging and troubleshooting.

   Solution: First, try to reinstall the Ubuntu system to ensure that the system files are not damaged. Secondly, check the system log file (/var/log/syslog) and Xorg log file (/var/log/Xorg.0.log) for error messages to find possible instruct. Finally, consider contacting the Ubuntu community or professional technical support for help.
