Hello, I must switch from 'gdm3' to 'ligthdm' in a non interactive mode. I must make the switch in the 'preseed' file used to install the PC with PXE.
I've tried without success : echo "lightdm shared/default-x-display-manager select lightdm" | debconf-set-selections echo "gdm3 shared/default-x-display-manager select lightdm" | debconf-set-selections echo "sddm shared/default-x-display-manager select lightdm" | debconf-set-selections debconf-get-selections | grep lightdm lightdm lightdm/daemon_name string /usr/sbin/lightdm # Choices: gdm3, gmd3, lightdm, sddm gdm3 shared/default-x-display-manager select lightdm gmd3 shared/default-x-display-manager select lightdm lightdm shared/default-x-display-manager select lightdm sddm shared/default-x-display-manager select lightdm dpkg-reconfigure --frontend=noninteractive lightdm cat /etc/X11/default-display-manager /usr/sbin/gdm3 The content of of '/etc/X11/defautl-display-manger' is changed only in manual mode with the regular : dpkg-reconfigure ligthdm Any help will be appreciate. Best regards. Randy11.
