I did not run a planned and documented sequence of experiments. I did only what
was needed to find a fix for an immediate problem.
I ran dpkg-reconfigure locale as documented in clause 8.1.2 of the Debian
Reference. As I reported this changed the language and keyboard for
applications such as ssh.
I then checked that I could log out and log in again as root and as a user.
This failed since the greeter was not localised to fr-FR.UTF-8.
As I reported, dpkg-reconfigure changed the locale, but not the X11 keyboard
layout:
root@carros ~ localectl status
System Locale: LANG=fr_FR.UTF-8
VC Keymap: (unset)
X11 Layout: us
X11 Model: pc105
My attempt to repair this using localectl failed:
root@carros ~ localectl set-x11-keymap fr
Failed to set keymap: Access denied
I did not investigate to find out why access was denied. I did find a fix with
the reported file /etc/X11/xorg.conf.d/20-keyboard.conf adapted from an Arch
fix
for the same problem 11 years ago. This solved my problem. I did not need to
try Wayland.
