Auto-login on desktop no working method found yet

Question

I need a Raspberry PI to login on boot and execute a bunch of scripts. The bunch of scripts part is working fine.

For the auto-login, it isn't as cooperative. I work on a RPI that has had quite some modifications yet. It is on Raspbian installed with NOOBS. As I started working on it, it already started with a login GUI, getting me to the desktop.

Here is what I tried so far to skip the login screen :

sudo raspi-config

And desktop log in as user 'pi' at the graphical desktop. Reboot to see the changes.. Nothing.

Then I tried the several /etc/inittab lines :

1:2345:respawn:/bin/login -f pi tty1 </dev/tty1 >/dev/tty1 2>&1
1:2345:respawn:/bin/login -f pi tty1 / dev/tty1 2>&1

And the variants with different space placements. I forgot some unfortunately.

Finally, I tried putting these in /etc/lightdm/lightdm.conf

autologin-user=identifiant
autologin-user-timeout=0
pam-service=lightdm-autologin

Nothing worked. So I'm starting to lose hope. I can't know what has been done before on this RPI to get it not working.

If you have any idea where to search, or any alternative solution, I'll take it.

Thanks.

Answer 1

I faced similar problem and resolved it using following

sudo apt-get install --reinstall lxsession

I got a hint about this from .xsession-errors file. The error in this file was

/usr/bin/x-session-manager: 33: exec: /usr/bin/lxsession: not found

I finally found the solution to my problem.

It might help some lost souls.

My RPI turned out to use XDM as its default display manager. And it appears that XDM doesn't allow at all autologin.

So what I did :

sudo dpkg-reconfigure lightdm

And then, the raspi-config stuff worked without any problem.

We had a similar problem and found that commenting out the following line from /etc/lightdm/lightdm.conf fixed the issue:

Before:

autologin-session=LXDE-pi-x

After:

# autologin-session=LXDE-pi-x
