Hi Takashi,

I followed your instructions to switch runlevels with the nomodeset option.
Here are the detailed results:
Runlevel 3:

    After booting into single-user mode with nomodeset, I switched to runlevel
3 using init 3.
    The system functioned correctly in runlevel 3. I was able to log in and use
the command-line interface without issues.
    I verified system functionality by running several basic commands (e.g.,
ls, pwd, top), and everything worked as expected.

Runlevel 5:

    When I switched to runlevel 5 using init 5, the system attempted to start
the graphical interface.
    However, the display went blank, indicating that the graphical user
interface did not load as expected.
    There were no visible error messages on the screen; it simply went blank.

Please let me know the next steps or if you need any additional information to
troubleshoot this issue further. Thank you for your assistance.

Best regards,

Jacopo
