Fixing Black Screen after Suspend on Ubuntu 21.04

Ubuntu 13

If you’re an Ubuntu 21.04 user and have experienced a black screen after suspending your system, you’re not alone. This issue can be frustrating and may seem difficult to resolve. However, there are several solutions you can try to fix this problem. In this article, we will explore these solutions in detail.

Quick Answer

To fix the black screen after suspend issue on Ubuntu 21.04, you can try disabling Nvidia services, booting with advanced options, installing a stable kernel version, or resetting themes.

Understanding the Issue

The black screen after suspend issue typically occurs when the system fails to wake up properly from a suspended state. This can be due to various reasons such as incompatible hardware, a bug in the operating system, or incorrect settings.

Potential Solutions

1. Disabling Nvidia Services

If your system is using Nvidia graphics, the problem might be related to the Nvidia services – nvidia-hibernate, nvidia-resume, and nvidia-suspend. You can disable these services by running the following command in the terminal:

systemctl disable nvidia-hibernate.service nvidia-resume.service nvidia-suspend.service

In this command, systemctl is a system service manager command that allows you to control the state of the system and services. The disable option is used to disable services so they don’t start during boot time.

2. Booting with Advanced Options

Another solution you can try is booting with the “Advanced options for Ubuntu” in the BIOS and selecting the Linux Generic option instead of recovery mode. This can help recover the system and allow you to see the login screen again.

3. Installing a Stable Kernel Version

Sometimes, the issue might be due to the kernel version. In this case, you can try installing a stable kernel version that is known to work well with the suspend feature. You can download the desired kernel version from the Ubuntu kernel archive and install it using the following command:

sudo dpkg -i linux*

In this command, dpkg is a package manager command that installs, removes, and manages Debian packages. The -i option is used to install a package.

4. Resetting Themes

In some cases, broken themes can cause the black screen issue. To fix this, you can try resetting the themes back to default. You can do this by navigating to the Appearance settings and selecting the default theme.

Conclusion

While the black screen after suspend issue on Ubuntu 21.04 can be frustrating, there are several potential solutions that you can try. If none of these solutions work, it may be a known bug that requires a fix from the developers. In the meantime, you may need to disable the suspend feature altogether or wait for a fix to be released.

Remember, always back up your data before making any major changes to your system. If you’re not comfortable performing these steps on your own, consider seeking help from a professional or the Ubuntu community.
