    /etc/X11/xorg.conf is an optional file that most users have had no need for for most of the past two decades. The main exception in actual practice is that installation of proprietary NVidia drivers historically has created one. xorg.conf
    may be replaced by one or more files in optional directory /etc/X11/xorg.conf.d/.

    Please provide:

    output from: inxi -GSaz (from within an X session)
    /var/log/Xorg.0.log (only exists if using Xorg; may instead be found
    in ~/.local/share/xorg/)

    Users of dual GPUs (commonly termed "Optimus" when involving coupling of Intel iGPU with NVidia dGPU) usually need optional software for managing which GPU is used when and/or for what applications.

    I have installed Debian 12.9 from the live image on my System76 Oryx Pro (Intel Xe Graphic + nvidia 4060) yesterday.
    I have NOT installed the nvidia-driver yet (previous attempt failed and I re-installed fresh), only i915 and nouveau are installed.

    Now my second monitor connected via HDMI port is not detected.

    After after a while, I realized I am running Wayland. When trying to login using "GNOME on Xorg" it does not start although all xorg packages are installed, and I return to login screen.

    Your hardware appears to be newer than your operating system, so it will be only
    partially supported at best without either adding optional (backport) repo(s), and/or using a newer operating system than Bookworm.

    Inxi is misreporting your supposed "loaded" display drivers, which may be due either to a broken (WRT graphics) old inxi version, or the newness of your GPU(s)
    and/or CPU and/or chipset - or, because X is exiting so very quickly, before it is
    able to unload the inapplicable drivers that it succeeded to load. Inxi's listed
    as X having loaded virtually every display driver in existence for current GNU/Linux distributions. Absent for hardware you do have are Xe (FOSS) and (proprietary) NVidia. One of the loaded drivers, modesetting, does support various
    Intel and NVidia GPUs, likely including yours, but only with required kernel support available.

    Without proper drivers both available and installed, second displays are not supported, and primary displays typically have inadequate or no support. Due to the presence of two GPUs newer than the OS in your laptop, I suggest to upgrade to
    Debian Testing (Trixie) as the probable simplest way forward overall. Alternatively, start as the next step installing a backport kernel, to see whether
    or not a newer kernel alone might be sufficient for your individual needs. https://backports.debian.org/
