What should I do if I encounter a black screen when Ubuntu starts?

How to solve the black screen problem encountered when Ubuntu starts up

As a popular operating system, Ubuntu is widely used in personal and enterprise use. However, sometimes users may encounter a black screen problem when starting Ubuntu, which greatly affects the normal use experience. In this article, we will discuss some ways to solve this problem and provide concrete code examples.

  1. Update graphics driver

Black screen problems are usually related to the graphics driver. First, we can try updating the graphics driver to resolve the issue. This can be performed by following these steps:

Open Terminal (Ctrl Alt T) and enter the following commands to update the driver:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install ubuntu-drivers-common
sudo ubuntu-drivers autoinstall

These commands will automatically download and install the latest graphics driver for your system program.

  1. Modify the startup boot parameters

If updating the graphics driver does not solve the problem, then we can try to modify the startup boot parameters to fix the black screen problem. Please follow the steps below:

Press the Esc key at startup and select "Advanced Options" to enter the advanced options menu.

Select "recovery mode" in the menu to enter recovery mode.

In recovery mode, select "root" to gain root permissions.

Then, enter the following command in the terminal to modify the startup boot parameters:

nano /etc/default/grub

In the open file, find the following line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Modify it to:

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset"

Save the file and exit.

Next, execute the following command to update the GRUB configuration:

update-grub

Finally, restart the system to see if the black screen issue is fixed.

  1. Install other desktop environments

Sometimes, the black screen issue may be related to the desktop environment. If the above method still does not solve the problem, we can try to install other desktop environments to solve the problem. The following are several common desktop environments:

  • GNOME: sudo apt-get install ubuntu-gnome-desktop
  • KDE Plasma: sudo apt-get install kubuntu-desktop
  • Xfce: sudo apt-get install xubuntu-desktop
  • LXDE: sudo apt-get install lubuntu-desktop

After the installation is complete, log out of the current user and select Log in to the newly installed desktop environment. If the new desktop environment starts normally, the problem is resolved.

  1. Check Hardware Compatibility

Finally, if the above method still cannot solve the black screen problem, then it is likely that some hardware devices are incompatible with Ubuntu. One solution is to check hardware compatibility, specifically the graphics card and monitor.

First, we need to determine which graphics card model we are using. You can check it with the following command:

lspci -vnn | grep VGA

Then, use an internet search engine to find out whether the graphics card model is compatible with Ubuntu. If you find compatibility issues, you can try upgrading the graphics card driver or replacing a compatible graphics card.

Also, check the compatibility of your monitor. Make sure the monitor mode and refresh rate match Ubuntu's requirements.

Conclusion

There may be many reasons why Ubuntu encounters a black screen problem when starting, but we can solve it by updating the graphics driver, modifying the startup boot parameters, installing other desktop environments, and checking hardware compatibility. Solve the problem. Hope the above method is helpful to you. If the problem persists, please consider contacting the official Ubuntu community and forums for more detailed support and assistance.
