Did you try the fresh Trixie without forcing Xe?
Have you tried an IceWM (very lightweight) or any other non-Plasma session
instead
of of Plasma to confirm whether the internal is black there too? If not black
yours would more likely be a Plasma problem, not X or Wayland. Arandr is an
available GUI tool you could use instead of xrandr while running IceWM to try
rotating the internal, or getting it to light up.

In Fedora 42, X11 is available for Plasma, but not "supported" by its KDE team
members.

In fallback modes, such as when using nomodeset, modes are normally limited to
standard VESA modes, all of which are 4:3 modes, with possible exception of
1920x1080 with some hardware, and none of which (IIRC) are portrait. 1280x800 is
16:10, not among traditional VESA's standard repertoire.
>> Nomodeset is a troubleshooting workaround that never supports two displays.
Somewhere in your thread I thought I saw mention use of nomodeset in conjunction
with seeing both displays lit at once running Linux. I've never been able to
make
that happen with any distro or kernel on upwards of at least 50 computers.
Now should be better than later to try submitting a Debian bug report about
this.
It ought to be fixable if you don't have faulty mini firmware.
