How to restore Linux to its initial state interface.

There are several methods to try in order to restore the Linux system to its initial interface.

1. Reinstalling the operating system is the simplest way to reset the system to its original state. During the installation process, you can choose to format the hard drive, repartition it, and then reinstall the operating system, which will delete all existing data and configurations.
2. Utilize system restore feature: Some Linux distributions (like Ubuntu) offer a system restore feature that can revert your system back to a previous state. You can search for similar options in system settings or use relevant commands in the command line.
3. Use backup files: If you have a backup of your system, you can restore it to its initial state by copying the backup file to the appropriate location in the system.

No matter which method you choose, please make sure to back up important data in advance to prevent data loss.
