Troubleshooting Garbage Screen Issues
Here are some steps you can take to troubleshoot garbage screen issues in Ubuntu 23.10:
Step 1: Check Hardware Connections
Ensure that all cables are properly connected, and the graphics card is securely seated in its slot. If you have a spare graphics card, try using it to see if the issue persists.
