[Xubuntu] Auto-login Doesn't Work

Asked by Justin Rich on 2012-07-26

Xubuntu 12.04 on a Compaq Presario V2000 Laptop (yeah it's old)

So, I cannot get auto login to work period. I've already tried editing my /etc/lightdm/lightdm.conf file. This is what it reads:


I've tried changing it around, it appears the order doesn't change anything. I've also gone to Applications>System>Users and Groups and selected my user profile and checked the box that says that I don't have to put a password in (Suprisingly doesn't ask for the password to do this).

Anyways, all that happens is the greeter comes up and when I click on my name the screen flashes to a nosplash type display for about half a second and then goes back to the greeter without logging me in. I can kind of see some of the stuff it shows, it only took about 40 attempts... It was saying something about Plymouth failing and then something about the battery state. Any help would be greatly appreciated.

To login without password the user has to be in the nopasswdlogin group.
You can add a user with:
sudo gpasswd -a user_name nopasswdlogin

Justin Rich (justin-t-rich) said : #6

Negatron, this is effectively the same as clicking the check box for no password on login in the Applications>System>Users and Groups. I did try this method though and rebooted and it still does the exact same thing.

Justin Rich (justin-t-rich) said : #8

If you look at my question you can note that my lightdm.conf file is already setup the proper way. Still does not work.

andy@D420:~$ cat /etc/lightdm/lightdm.conf

Here is mine with autologin working, if you are missing any of the lines, add them

Justin Rich (justin-t-rich) said : #10

Negative, I changed mine to exactly what yours is, except my username and my user/greeter session is different because xubuntu. No change.

Justin Rich (justin-t-rich) said : #12

This is nothing new... Adding the # in front of any line in the config files just makes it a comment and whatever reads the file ignores it as code. Still not working.

Could install xdm or gdm and remove lightdm

Maybe review lightdm.log and syslog.

Justin Rich (justin-t-rich) said : #15

Going to bed now but will check those logs when I can. Where would I find those anyways?

Also, actionparsnip that's not really an answer to fixing a problem. That's throwing the problem away and getting a new one (possibly).

Still appreciate you guys looking at this though.

This is the only thing that stood out while looking at /var/log/lightdm/lightdm.log:

[+941.41s] WARNING: Could not call SetLanguage: GDBus.Error:org.freedesktop.Acc$

As for /var/log/syslog... That thing is huge! I used "grep "lightdm" syslog" and only had one entry:

Jul 27 07:16:00 justin-Presario-V2000-EZ617UA-ABA lightdm: pam_ecryptfs: Passphrase file wrapped

I did encounter something that would be useful to know for future reference as well. I use the standard terminal emulator that ships with xubuntu, I tried to Select all to copy the entire lightdm.log and it only copied what was currently on the screen. What method would be the best for copying large amounts like this? And should I be using something different for working in the terminal? I remember using Konsole when I was on regular Ubuntu.

Thanks guys!

Sam_ (and-sam) said : #18

Since suggested workarounds not help on Xubuntu rather report a bug or contact Xubuntu community if the issue is known there.

> standard terminal emulator that ships with xubuntu

Maybe look into preferences keyboard bindings or it's manpage.

> Select all to copy the entire lightdm.log

Why not copy the file then or redirect the content into a file?

Can you help with this problem?
