Having zero luck getting Arch auto login working

road hazard · 05-26-2019, 10:17 PM

Used the Zen installer to install Arch. Lightdm/Cinnamon.

Followed this guide: https://wiki.archlinux.org/index.php...rl:vnq64bvr%5D

and I'm having zero luck getting auto login working.

Lightdm.conf

Code:

[Seat:*]
#type=local
#pam-service=lightdm
#pam-autologin-service=lightdm-autologin
#pam-greeter-service=lightdm-greeter
#xserver-backend=
#xserver-command=X
#xmir-command=Xmir
#xserver-config=
#xserver-layout=
#xserver-allow-tcp=false
#xserver-share=true
#xserver-hostname=
#xserver-display-number=
#xdmcp-manager=
#xdmcp-port=177
#xdmcp-key=
#unity-compositor-command=unity-system-compositor
#unity-compositor-timeout=60
#greeter-session=example-gtk-gnome
#greeter-hide-users=false
#greeter-allow-guest=true
#greeter-show-manual-login=false
#greeter-show-remote-login=true
#user-session=default
#allow-user-switching=true
#allow-guest=true
#guest-session=
session-wrapper=/etc/lightdm/Xsession
#greeter-wrapper=
#guest-wrapper=
#display-setup-script=
#display-stopped-script=
#greeter-setup-script=
#session-setup-script=
#session-cleanup-script=
#autologin-guest=false
autologin-user=roadhazard
#autologin-user-timeout=0
#autologin-in-background=false
autologin-session=cinnamon
#exit-on-failure=false

pam.d/lightdm

Code:

auto        sufficient  pam_succeed_if.so user ingroup nopasswdlogin
auth        include     system-login
-auth       optional    pam_gnome_keyring.so
account     include     system-login
password    include     system-login
session     include     system-login
-session    optional    pam_gnome_keyring.so auto_start

Those are the two files I edited. My account (roadhazard) is in the autologin and nopasswdlogin groups. When my computer boots, I get a black screen. If I move to tty2 and type my name at the login screen, it immediately brings up the desktop. (I don't have to type my password.... just my username and THEN it brings up the desktop. I think I'm really close but can't get it working.

Stupid question, but you've enabled the lightdm service so it runs at boot?

No such thing as a stupid question here in newbie land!

I went into my SystemD GUI and see that lightdm is enabled and started. Does that qualify it to be started at boot or do I need to dig deeper?

No need to dig deeper, the enabled in SystemD is what I was looking for.

I can tell you that this works.

/etc/systemd/system/getty@tty1.service.d/override.conf

Code:

[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin username --noclear*%I $TERM

~/.bash_profile

Code:

if [[ ! $DISPLAY && $XDG_VTNR -eq 1 ]]; then
  exec startx -- -dpi 100
fi

autologin-user=roadhazard

Make sure the username is correct. Sometimes you'll have a space after it, which might get in the way, or sometimes is required. Interpreters can be "quirky", version changes between can change those quirks.

Not sure why you changed /etc/pam.d/lightdm? And is - the comment character? Seems more like # is the comment character based on other files in that path.

Isn't cinnamon a fork of gnome? There's a gui user manager with a toggle for auto login. Or so they say, never really gone down that rabbit hole. I tend to run level 3 / multi-user.target and use startx to go GUI. Too many painful memories of broken video drivers and reinstalls to overcome GUI starts, versus changing a configuration file and rebooting. Since proprietary drivers get undone every time you update and the kernel changes.

BITD we used a autologin.c program and put it in the /etc/inittab for one of those [a][ge]tty things.

But *sigh* systemd no longer does things the traditional way.
