Re: Need help: internal display of 8" mini laptop blank, only external HDMI display working

Please provide output from inxi -GSaz booted without nomodeset and with external
display connected. It provides a friendly combination of much of the information
you already provided, and may provide additional value.

The N100 CPU was RTM in early 2023, well after launch of Debian 12 in August 2021:

Required support for it is unlikely to be present in 12.11. Newer kernel and/or X
packages from backports are unlikely adequate for needed support.
Whether or not you have already tried the guc/huc command line options there I
suggest you visit <https://wiki.archlinux.org/title/Intel_graphics> and give all
the help there a try.
Debian 13 Trixie is well along in development with full version freeze in effect
as of last month. A fresh Trixie installation instead of upgrade from Bookworm may
be the path you need to take. If this does not work, I suggest you file a bug report.
You may consider testing a live media or an installation of a distro that stays
more current than Trixie will be when released. All the Alder Lake bugs /should/
be gone by now in the latest of everything, /including Trixie/. Fedora 42 was
released in April. openSUSE Tumbleweed gets released as often as 7 days per week.
I use both in addition to Trixie and Bookworm. If in such testing the problem
remains, surely an upstream bug is involved.
Nomodeset is a troubleshooting workaround that never supports two displays.
