[Bug 1508146] Re: Alt+left/right arrows switch between tty consoles (Gnome Shell vanishes), cannot disable

[Yannick]

In my case, I traced the issue to the keyboard-configuration package
postinst script, which ends up calling 'setupcon --force --save' which
in turn calls 'kbd_mode -u'

To reproduce:
sudo apt install --reinstall keyboard-configuration

setupcon documentation states:
"--force    Do not check whether we are on the console.  Notice that you can be forced to hard-reboot your computer if you run setupcon with this option and the screen  is  controlled by a X server."

It looks like the checks to avoid this behavior while a graphic
environment is active don't work in the context of the installer.
