Description Flags
lightdm.log from a failed login attempt to Xfce and a successful one to fluxbox none

Description hannes 2012-07-02 07:42:39 UTC 
Description of problem:
Since this morning I was not able to log in to my Xfce 4.10 session. I use the repo provided by Kevin. I tried to set selinux to permissive but this didn't help. I finally found the possibility to log in to a fluxbox session and I looked into the yum history to see some changes related to this.
I downgraded accountsservice to the stable version
rpm -qa accountsservice\*
accountsservice-0.6.18-1.fc17.x86_64
but it was still not possible to login. Previously the version of accountsservice was accountsservice-0.6.21-2.fc17.x86_64, which I installed yesterday from updates-testing.

Version-Release number of selected component (if applicable):
rpm -qa lightdm\*
lightdm-gtk-1.1.6-3.fc17.x86_64
lightdm-1.2.2-15.fc17.x86_64
lightdm-gobject-1.2.2-15.fc17.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Select Xfce Session in lightdm
2. Select user and enter password

Additional info:
I don't know which additional info would be relevant. I just could say that until this morning everything worked perfectly.
Comment 1 Rex Dieter 2012-07-02 17:14:02 UTC 
When it fails, can you find anything interesting in any of
~/.xsession-errors
or
/var/log/lightdm/*.log 
?

Comment 3 hannes 2012-07-02 17:21:37 UTC 
I found something, first I logged into fluxbox and logged out again to try if Xfce will work. It didn't work and so I logged into fluxbox again.
Comment 4 Rex Dieter 2012-07-02 17:34:09 UTC 
[+26.29s] DEBUG: Session 906 running command /etc/X11/xinit/Xsession startxfce4
[+26.37s] DEBUG: Registering session with bus path /org/freedesktop/DisplayManager/Session1
[+26.65s] DEBUG: Session 906 exited with return value 0

So, during those 30 seconds, nothing happens?
Comment 5 hannes 2012-07-02 17:35:53 UTC 
Well the screen went black and after a blinking cursor appeared in the upper left corner lightdm came up again.
Comment 6 Rex Dieter 2012-07-02 17:36:08 UTC 
and for that given failed session, nothing in ~/.xsession-errors ?
Comment 7 hannes 2012-07-02 17:44:41 UTC 
Ok, just tried and there is absolutely nothing in .xsession-errors after a failed login attempt. It's empty. I removed all .xsessions files before logging out and after trying to login I checked it from a virtual console and it was empty.
Comment 8 Rex Dieter 2012-07-02 18:07:10 UTC 
I'm out of ideas, and can't reproduce this. :(
Comment 9 hannes 2012-07-02 18:12:18 UTC 
Sorry, I now probably know the cause of this. I tried to undo changes I made to fix a bug with Qt and probably this was what caused the failure to start Xfce. 
I am really sorry for missing this one and thanks for your help and sorry for stealing your time.
