While Xorg _detects_ the intel chip on the motherboard, it tries to use the
Nvidia card.

What is missing from your logfile is your monitor telling the graphics card
what it is capable of via EDID. Maybe your monitor is too old to support EDID.
My suspicion is that this is the cause of the fatal error "no screens found".

In that case, you'll have to specify in your xorg.conf what your monitor is
capable of. You should at least add a “Modes” line to the “Display” subsection
of the “Screen section”. Look at the “DISPLAY SUBSECTION” section in
xorg.conf(5).

Here's an example for the screen section using a HD monitor:

Section "Screen"
        Identifier      "Screen0"
        Device          "Card0"
        Monitor         "Monitor0"
        DefaultDepth    24
        SubSection "Display"
            Depth   24
            Modes   "1920x1080"
        EndSubSection
EndSection

Consult the documentation of your monitor to see which modes it supports.

You may also have to add “ModeLine” entries to the “Monitor” section of your
Xorg.conf.
