pantheon-greeter do not allow to login

[Aleksei Tcelishchev]

fresh install luna beta amd_x64 on notebook with ati x1200 video card

pantheon-greeter starting correctly but do not allow to login
greeter window just continue reappearing after submiting password

also the is no any options to select another desktop env or guest session

[Aleksei Tcelishchev (casualuser)]

livecd starting well so it seems everething ok with X and video driver

[Aleksei Tcelishchev (casualuser)]

allow-guest=true in /etc/lightdm/lightdm.conf also do not change anything

[Aleksei Tcelishchev (casualuser)]

so it's really quite strange situation with user profiles here

previously there was old /home partition mapped while installing

right now I've just get fresh installation works with /home partition placed at the same partition as /

then I've mounted old /home partition, moved new working user profile there with rename and renamed old user profile to actual path

and so it's again falled while logging in...

chown -R doesn't change anything

then I've tried to rename old profile folder to smth else and move fresh profile folder to actual paths

and so it's again falled while logging in...

it seems there is something with profile env but .Xauthority looks well and have proper permissions

what else there may be checked/verifyed ?

there is some text strings appears while logging in but it's not possible to read it and not so clear where is it's logged

Try installing unity-greeter and setting the greeter session in sudo nano /etc/lightdm/lightdm.conf to unity-greeter. If the bug persists, it's probably not just a patheon-greeter bug.

[Aleksei Tcelishchev (casualuser)]

using unity-greeter give out the same issue

and if guest session via unity-greeter started then it launched well but display msg like
The volume "home" has only 0 bytes disk space remaining.

but there is at least 4Gb free disk space

so I'm just not sure which logs can I check to find out what's happening there

any suggestions?

[Aleksei Tcelishchev (casualuser)]

so I've installed xfce and tried to login to xfce with user creds

still the same - greeter session just restart or so

and guest session also works well for xfce

how to debug/trace what's the fault point?

[Aleksei Tcelishchev (casualuser)]

ok

so it seems I've found and fixed the source of the issue

it have been caused by separate /home partition resize performed some time ago
in some cases partitions checks during install passed well but starting session with pantheon failed

right now I've backed everything and recreated partition with format
then after remount and switching to using that separate partition for home it started to boot as well as should do

if you still need some logs from pantheon to look at then it seems I still can provide some from backed up system
just let me know which files required

[Aleksei Tcelishchev (casualuser)]

and still the same

right now I still have /home placed at the same small partition as the /

because if /home will be moved to another partition then it fail to load pantheon

and if it moved back to system partition with / then pantheon still keep falling to load

is there any extension logging for pantheon enabled ?

partitions looks like this:

/dev/sda1 ntfs
/dev/sda2 swap
/dev/sda3 ext3 /
/dev/sda4 ext3 /home

It seems that I'm also affected by this bug. I tried autologin but it doesn't help.

I have a fresh install that worked great for several reboots. Before the last reboot I added ppa https://launchpad.net/~marek-tyburec/+archive/gtelevize - I can't login since then (but I don't thing it's because the PPA).

I don't have any idea how to debug this any further yet.

[Jan Onesork (janonesork)]

This seems to be the same issue as described here https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/871667

At login screen you can switch to terminal (CTRL+ALT+F2), login as root and type this command:

chown -R username:username /home/username

It fixes the problem for now.

[Heath Paddock (heathbar)]

I'm having the same error using the radoen open source driver. Things I've tried:

chown -R username:username /home/username
mv ~/.Xauthority ~/.Xauthority.backup

both ~/.xsession-errors and /var/log/lightdm/x-0-greeter.log contain the same critical error:

~/.xsession-errors
** (pantheon-greeter:9408): CRITICAL **: lightdm_user_get_real_name: assertion `LIGHTDM_IS_USER (user)' failed

/var/log/lightdm/x-0-greeter.log
** (pantheon-greeter:13541): CRITICAL **: lightdm_user_get_real_name: assertion `LIGHTDM_IS_USER (user)' failed

[Heath Paddock (heathbar)]

I ran:
sudo apt-get purge pantheon elementary-desktop
sudo apt-get install pantheon elementary-desktop

and now I can at least log in. There is still some weirdness--the wallpaper is white and can't be changed--but the computer is usable now.

[Waldemar Biller (wbiller)]

I expirienced this problem today after installing elementary-desktop on an fresh Xubuntu install. After purging the Xubuntu session I was not able to login to the Pantheon session. Deleting lightdm.conf and recreating it with dpkg-reconfigure pantheon-greeter I was still stuck at the login screen. What helped me was adding the user-session to lightdm.conf. The session name is Pantheon.

My lightdm.conf now looks like below.

[SeatDefaults]
greeter-session=pantheon-greeter
user-session=Pantheon

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Raphael Isemann (teemperor)]

This bug is no longer valid as the greeter can't do anything against wrong permissions on system files or deinstalled system software. When you experience any of the above described behavior, report a _NEW_ bug.
