The user is experiencing an error message 'Error: EDID Checksum is invalid, remainder is 128' when logging in to Fedora. This issue affects users who have installed Fedora on a hardware device with a non-standard display configuration.

This error can be frustrating as it prevents the user from accessing their desktop environment and performing tasks on their system.

💡 Why You Are Getting This Error

  • The EDID (Extended Display Identification Data) checksum is invalid due to a mismatch between the expected and actual display settings. This issue may occur when the system detects an external monitor or display device that is not properly configured.
  • Another possible cause could be a hardware issue with the graphics card or display device, which is causing the system to incorrectly detect the display configuration.

🚀 How to Resolve This Issue

Resolving EDID Checksum Issues using Fedora's Built-in Tools

  1. Step 1: Step 1: Identify and list all connected displays. To do this, open a terminal as an administrator and run the command 'ls /sys/fb/i915/edid' to display the EDID data for each connected display.
  2. Step 2: Step 2: Check if any of the listed displays are not properly configured or recognized by the system. You can use the 'cat' command to view the contents of the EDID file for a specific display, e.g., '/sys/fb/i915/edid/0'.
  3. Step 3: Step 3: If the issue persists, try running the command 'sudo edid-db --update' to update the EDID database. This may resolve any issues with the checksum.
  4. Step 4: Step 4: If none of the above steps resolve the issue, you can try using an external display or monitor that is properly configured and recognized by the system. This will help isolate whether the issue is hardware-related or not.

Resolving EDID Checksum Issues using Linux Command Line Tools

  1. Step 1: Step 1: Identify the display configuration file that is causing the checksum issue. You can use the 'find' command to search for files containing EDID data, e.g., '/usr/lib/dri/i915-edid.bin'.
  2. Step 2: Step 2: Check if the display configuration file is correctly formatted and contains valid EDID data. You can use a hex editor like 'hexdump' or 'xxd' to inspect the contents of the file.
  3. Step 3: Step 3: If the issue persists, try updating the X.Org configuration files using the command 'sudo update-rc.d xorg default'. This may resolve any issues with the display configuration.

💡 Conclusion

To resolve the EDID Checksum error in Fedora, you can try using the built-in tools or Linux command line tools to identify and resolve any hardware-related issues. If none of these methods work, it may be necessary to seek further assistance from a system administrator or IT professional.
