How to Fix a Frozen Screen on Ubuntu 24 Desktop Troubleshoot

A frozen screen on Ubuntu 24 can be frustrating, but it’s a common issue that can often be resolved without needing to reinstall your operating system. In this guide, we’ll walk you through simple and effective solutions to get your desktop back to normal.

1. Force Close Unresponsive Applications

Unresponsive applications are a frequent cause of freezes. Here’s how to close them:

• Shortcut Method: Press Ctrl + Alt + Esc to activate the kill cursor. Click on the frozen application window to close it.
• Alternatively, press Alt + F4 to close the currently active window.

2. Restart the Desktop Environment

For GNOME users, restarting the desktop environment can unfreeze the system:

• Press Alt + F2, type r, and press Enter.
• For other desktop environments, you might need to use specific commands to restart the environment.

3. Switch to a Virtual Console

A virtual console allows you to bypass the graphical interface and troubleshoot from the terminal:

• Press Ctrl + Alt + F3 to switch to a terminal.
• Log in with your username and password.
• Restart the display manager by running:

  sudo systemctl restart gdm
  

  If you’re using LightDM or another display manager, replace gdm with the appropriate name.

4. Check System Resources

Excessive resource usage can cause freezes. Here’s how to check:

• Switch to a terminal with Ctrl + Alt + F3.
• Run the command:

  top
  

  Identify any resource-intensive processes and terminate them using:

  kill -9 <PID>
  

5. Restart Your System

Sometimes, a full system restart is the quickest fix:

• In the terminal, run:

  sudo reboot
  

• If the system is entirely unresponsive, hold the power button for 5-10 seconds to force a shutdown.

6. Update and Upgrade Ubuntu

Keeping your system updated can prevent future freezes:

• Boot into a terminal or recovery mode.
• Run the following commands:

  sudo apt update && sudo apt upgrade
  

7. Check Disk Space

A full disk can cause performance issues, including freezes:

• Check disk usage with:

  df -h
  

• Delete unnecessary files to free up space.

8. Address Graphics Driver Issues

Outdated or incompatible graphics drivers can lead to freezes:

• Update drivers with:

  sudo ubuntu-drivers autoinstall
  

9. Boot into Recovery Mode

If none of the above solutions work, try recovery mode:

• Restart your system and hold the Shift key during boot to access the GRUB menu.
• Select Recovery Mode and choose options like "Repair Broken Packages" or "Resume Normal Boot."

10. Check Hardware Issues

If software fixes don’t work, you might be dealing with hardware problems:

• Ensure all cables are securely connected.
• Check for overheating components or failing hardware like the GPU.
