Analysis and solution of the problem that the Ubuntu black screen cannot access the system

Sometimes when we use the Ubuntu server image as the desktop environment, it turns black when we boot up. What is the reason for the black screen? Here are some problem solving strategies to try.

1. Check hardware connections

Make sure that the computer power supply and monitor are connected properly. Check whether the monitor power cable, VGA/HDMI/DVI cable are plugged in properly and whether the power switch is turned on.

2. Troubleshooting drive problems

If a black screen problem occurs after installing Ubuntu or updating the graphics card driver, it may be caused by incompatible drivers. Try to enter recovery mode, reinstall or rollback the graphics card driver at the command line.

3. Modify Startup Options

Select Ubuntu from the Grub menu and press e to enter editing mode. Find the line beginning with "quiet splash" and replace it with "nomodeset". Press Ctrl+X or F10 to start the system.

4. Update system

The black screen problem may be caused by errors or missing system components. Use recovery mode or press Ctrl+Alt+F3 to enter the command line interface, log in and run the following command to update the system:

 sudo apt update sudo apt upgrade sudo apt dist-upgrade

5. Check drawing settings

If you use multiple monitors or video cards, there may be a configuration conflict that causes a black screen. Try to fix the problem by adjusting the display layout, changing the resolution, or disabling/enabling additional graphics adapters.

6. Check Xorg configuration

The black screen problem may be related to the Xorg server. Check and edit the/etc/X11/xorg.conf file to ensure that it is configured correctly and compatible with your hardware.

7. Reinstall the desktop environment

If the problem only occurs in a specific desktop environment (such as Unity, GNOME, KDE, etc.), try reinstalling the desktop environment or switching to another available desktop environment.
