Depends on what Display Manager you use:
If you use GDM you have to edit the file /etc/gdm3/greeter.gconf-defaults
And add the line or just take away the hash:
- Code: Select all
/apps/gdm/simple-greeter/disable_user_list false
and as root
- Code: Select all
dpkg-reconfigure gdm3
http://wiki.debian.org/GDMMDM has the file /etc/mdm/mdm.conf
