Hi Takashi,

Thank you for your continued assistance. I followed your instructions to
uninstall the xf86-video-nouveau driver. Here is a detailed account of the
steps I took and the results:
Steps Taken:

    Booted into runlevel 3.
    Uninstalled the xf86-video-nouveau driver using:


    sudo zypper rm xf86-video-nouveau

    Rebooted the system.
    Tested the X server with Xorg -retro.

Results:

    Unfortunately, nothing has changed. The X server still fails to start with
the same no screens found error.
    Upon rebooting, the system was stuck in runlevel 3 and could not load any
GUI even with the 5.x kernel. This behavior persisted even after multiple
attempts to start the X server.

Rollback to Previous State:

    Luckily, I had created a snapshot with snapper before removing the
xf86-video-nouveau driver.
    I performed a rollback to that snapshot by booting it in read-only mode.
    The system is now back to its previous state, and the old kernel works as
usual with the GUI.

Given these outcomes, it seems that removing the xf86-video-nouveau driver did
not resolve the issue and instead led to additional complications. I am
currently back to the original state with the nouveau driver reinstalled.

Could you please provide further guidance on how to proceed? Is there an
alternative configuration or driver that might help resolve this issue? Your
expertise is greatly appreciated.

Best regards,

Jacopo
