Regardless of whether I boot to a GUI or to the console, I always want a password enabled on all of my machines.

I've looked at as many tutorials as I can find regarding this, and although there are apparently a myriad of ways to make debian boot to x and login automatically, I'm not using any of them that I can see. When I use the raspi-config script to set to boot GUI on startup, it bypasses my user password entry. As I have more than one user, this does not work.

So this question is, "How do I securely boot into x-server, maintaining a password before entering the GUI on Raspbian?"


The code on the line beginning 'sed' appears to set an auto-login function, if I don't misunderstand?

do_boot_behaviour() {
  whiptail --yesno "Should we boot straight to desktop?" 20 60 2
  if [ $RET -eq 0 ]; then # yes
    update-rc.d lightdm enable 2
    sed /etc/lightdm/lightdm.conf -i -e "s/^#autologin-user=.*/autologin-user=pi/"
  elif [ $RET -eq 1 ]; then # no
    update-rc.d lightdm disable 2
  else # user hit escape
    return 1
  • Do you have GDM installed then?

  • How do I figure out what packages I would need? And it appears that the raspi-config script is doing this, unless I misunderstand? See edited question for code snippet.

In /etc/lightdm/lightdm.conf, find the line that says


and comment it out; it should look like


You will have to do this as root.

  • I've done this over SSH, but I will have to wait until I get home from work to check its efficacy. I'll let you know. Did you get that location from the code above, or did you know this some other way?

  • It's the 'sed' line. Basically saying to replace the commented auto-login line in that file with an uncommented one and a specified user. Right?

  • @zenbike Right, I deduced the solution from the sed script. Jul 28, 2012 at 15:33
  • So, while it does cause the pi to require a login, it does not use GDM, rather, the login is required in the console, and the GUI no longer starts until I manually input startx.
