Dark X screen on a raspberry Pi2

Hi,

I installed a bookworm Debian on a raspi2 from
https://raspi.debian.net/daily-images/
The Pi boots and works well.
Then installed lxde, but the screen turns black when ligthdm launches.

I don't know if something comes from X settings, but I can see
[ 692.638] (II) modeset(0): Damage tracking initialized
[ 692.638] (II) modeset(0): Setting screen physical size to 338 x 270
in /var/log/Xorg.0.log

Seeing that there was an update of the firmware package
https://raspi.debian.net/tested-images/
I took it from
https://ftp.debian.org/debian/pool/non-free-firmware/r/raspi-firmware/
and installed it with a dpkg -i.
But I still have the same thing.

I tried to set a /etc/X11/xorg.conf.d/99-monitor.conf
which seems to be taken into account at first from the log.
Yet, still no screen.

I join both the config file I'm trying 99-monitor.conf
and the resulting Xorg.0.log.

Any help appreciated.
