### systemd and autologin

by fsmithred » Wed Jul 09, 2014 11:49 am

I'm putting these links here for later reference. I did get autologin to console working in sid with systemd. At this point, I don't know what we need to do about it. Have to see how live-* handles it.

i can confirm the information provided in the second link (archwiki) works in VT on sid with systemd (built today). AFAIK also works with all the live-* stuff without issues.

Right now in sid, live-* seems to not be handling autologin. I tried a bunch of combinations of "components=" and "nocomponents=" on the command line (booting a snapshot iso in vbox that was created August 31), and nothing seemed to work. I tried with lightdm, login, openssh-server, sudo, user-setup and I think a couple of other configs, in various combinations, with no effect whatsoever. No sudo with "components=sudo", no ssh host keys with "components=openssh-server", and no autologin with any of it.
To get autologin to the desktop, edit etc/lightdm/lightdm.conf -
- Uncomment the second instance of "#autologin-user=" and add the user name. (It's the one in the section labeled [SeatDefaults], not the one in "# Seat Defaults")
- Restart lightdm. (systemctl stop|start|restart lightdm)
To get autologin on the console, here are the directions copied from the archwiki page linked above.
NOTE: Replace "(*slash*)" with "/" wherever it appears below. And replace "username" with your user's login name.

> Create the following file (and leading directories):
> (*slash*)[email protected]
> /autologin.conf
> [Service]
> ExecStart=
> ExecStart=-/sbin/agetty --autologin username --noclear %I 38400 linux

To get more than one virtual console with autologin, here are instructions modified from the archwiki's systemd FAQ. (changed /usr/lib/systemd/system to /lib/systemd/system)
https://wiki.archlinux.org/index.php/Sy ... _gettys.3F

> How do I change the default number of gettys?
> Currently, only one getty is launched by default. If you switch to another tty, a getty will be launched there (socket-activation style). In other words, [Ctl] [Alt] [F2] will launch a new getty on tty2.
> By default, the number of auto-activated gettys is capped at six. Thus [F7] through [F12] won't launch a getty.
> If you want to change this behavior, then edit (*slash*)etc/systemd/logind.conf and change the value of NAutoVTs. If you want all [Fx] keys to start a getty, increase the value of NAutoVTs to 12. If you are forwarding journald to tty12, increase the value of NAutoVTs to 11 (thus leaving tty12 free).
> You can also pre-activate gettys which will be running from boot.
> To add another pre-activated getty, simply place another symlink for instantiating another getty in the (*slash*)etc/systemd/system/getty.target.wants/ directory:

Code: Select all
  `# ln -sf /lib/systemd/system/getty@.service (*slash*)[email protected]
  # systemctl start [email protected]
  `

> To remove a getty, simply remove the getty symlinks you want to get rid of in the etc/systemd/system/getty.target.wants/ directory:

Code: Select all
  `# rm (*slash*)etc/systemd/system/getty.target.wants/getty@{tty5,tty6}.service
  # systemctl stop [email protected]
  [email protected]
  `

Edit: changed path to agetty (/sbin/agetty)

Well, creating additional gettys works, but getting autologin to work on them isn't working for me. I made two additional virtual consoles (tty2 and tty3) and set autologin on tty1 and tty2. Only tty3 gives me a login prompt, and the others just give me a blinking cursor.

Got it!
Couple of things -
- I. disabled autologin on tty1, because systemd reserves tty1 for the graphical system, if you boot into graphical mode. (deleted the [email protected]
e.d directory and the autologin.conf it contained)
- 2. Changed the path for agetty in autologin.conf

Code: Select all
  `[Service]
  Type=simple
  ExecStart=
  ExecStart=-/sbin/agetty --autologin username --noclear %I 38400 linux`

Once again, replace username with your user's login name.
Edit: So, this presents a problem if someone wants to boot into an autologin console, but only wants to do that sometimes. Right now, we have runlevel 3 set for no display manager (and no graphical desktop), which drops you to a text login on tty1. But tty1 is reserved for when you want to boot into graphical mode, so we shouldn't set it to autologin.
There's probably a simple way to deal with it, but I don't know what that is. Maybe a script that detects you're booting into console and then creates the autologin.conf for tty1 or a way to get dropped to tty2 instead of tty1 when you boot.
Or maybe live-config can do it, and I just don't know how.
