Dear Maintainer, When editing /etc/lightdm/lightdm.conf in order to enable autologin-user, on some boots, the setting sometimes have no effects, and the autologin doen't happen everytime. But as a Workaround, if the autologin-timeout is set (to 5 seconds for example), then after 5 seconds waiting on the login screen, the autologin always happen. This workaround is not perfect, it's consuming time to load the user login screen for nothing and wait for nothing; also I'm not sure of what happen on a slow computer if 5 second is not enough ? I have this problem on all of my computers since Debian Stretch. Never had before, with Debian Jessie. Thank you in advance ! Best regards, Julien ROBIN
