grep -r system.conf /usr/share/dbus-1//usr/share/dbus-1/system.conf: <include ignore_missing="yes">/etc/dbus-1/system.conf</include>I do not have this file as well. I suggest Pierre to compare config files of live and installed environments.I recommend to read <https://www.debian.org/releases/bookworm/amd64/release-notes/ch-upgrading.en.html>and the similar document for bullseye. My guess is that the non-free-firmware repository may be missed on this machine and it may have impact on issues with Xorg.
I had two extra files in /etc/dbus-1 # ls -l /etc/dbus-1/ total 8 lrwxrwxrwx 1 root root 30 3 avril 2021 session.conf -> /usr/share/dbus-1/session.conf drwxr-xr-x 2 root root 4096 16 sept. 2023 session.d lrwxrwxrwx 1 root root 29 3 avril 2021 system.conf -> /usr/share/dbus-1/system.conf drwxr-xr-x 2 root root 4096 1 sept. 18:04 system.d # grep -r system.conf /usr/share/dbus-1/ /usr/share/dbus-1/system.conf: <include ignore_missing="yes">/etc/dbus-1/system.conf</include> I deleted them # rm /etc/dbus-1/session.conf /etc/dbus-1/system.conf And X server is starting !!!! Thank you all. I guess upgrading directly from debian 9 to debian 12 prevented a script to remove these files. I do not think it was related to non-free-firmware repository (Here is my sources.list below) deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware deb http://deb.debian.org/debian-security/ bookworm-security main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian-security/ bookworm-security main contrib non-free non-free-firmware deb http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm-updates main contrib non-free non-free-firmware deb http://deb.debian.org/debian bookworm-backports main contrib non-free non-free-firmware deb-src http://deb.debian.org/debian bookworm-backports main contrib non-free non-free-firmware
