Hello,
I have installed Debian9 on 2 pc at home, went through the installation menues.. perhaps too quick.. and now my keyboard is a qwerty instead of a QWERTZ setup. How to change it to the the correct setup

# dpkg-reconfigure keyboard-configuration
# service keyboard-setup restart
from
https://wiki.debian.org/Keyboard
with pc 105 and german dont work
I see that de-latin1 is nomore available like previously setup i made on some linux
any help is welcome

Works for the active session.
And it is gone at reboot > how to make permanent..

What desktop environment are you using? There may be DE specific configuration settings somewhere.

But since this is a new install, the simplest thing may be to log in to a console login (or ssh in from another computer) and remove/move the contents of regular user's home folder (including the dot files).

Actually, just the dot files should be good enough:

Do this while you are NOT logged into a graphical session.

After this, log in to a graphical session, and whatever DE you're using should hopefully create default settings that take into account the german setting you used for dpkg-reconfigure keyboard-configuration

via locale settings.

How precisely? I am trying few time without success.
Thanks.

Start the install process over and see if it selects or has the ability to select the correct keyboard??

What command?
Till now, I have to use "setxkbmap de" after each reboot.. and when I am not in the house, the family members has to folow the rule "z" is a "y". Not funny.
On a samsung nc10 with xfce,
dpkg-reconfigure keyboard-configuration
udevadm trigger --subsystem-match=input --action=change
worked. But not on that bluetooth keyboard k400r connected to a HP 8200 with gnome (last Debian stable).

if that works, then it must be possible to make that a Xorg setting:
