 Posted: Wed Aug 24, 2016 8:59 am Post subject: [SOLVED]lightdm: immediate log out after log in |
 |
|
Hi
On a new installation: | Code: | Linux pteropus 4.4.6-gentoo #1 SMP Tue Aug 23 15:32:04 CEST 2016 x86_64 Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz GenuineIntel GNU/Linux
|
i added lightdm and xfce.
dbus, consolekit and xdm are in rc-update: | Code: | consolekit | boot
dbus | default
xdm | default
|
(in xdm i have DISPLAYMANAGER="lightdm")
When i boot the computer i get the lightdm greeter, but after logging in, the greeter disappears and it looks like X is restarted (short flash of the nvidia splash screen), and the greeter reappears.

From this log i can see that my log-in attempt was successful, but immediately after that the session is closed | Code: | [+14.26s] DEBUG: Session pid=3555: Authentication complete with return value 0: Success

[+14.35s] DEBUG: Seat seat0: Session stopped
[+14.35s] DEBUG: Seat seat0: Greeter stopped, running session |
There are also a few wrnings/errors but i don't know if they are the problem: | Code: | [+0.00s] WARNING: Failed to get list of logind seats: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.login1 was not provided by any .service files

[+16.20s] WARNING: Error activating ConsoleKit session: GDBus.Error:org.freedesktop.ConsoleKit.Session.Error.AlreadyActive: Session already active
|
When i log in as root, it looks somewhat different: | Code: | [+147.80s] DEBUG: Session pid=3527: Continue authentication
[+148.02s] DEBUG: Session pid=3572: Authentication complete with return value 0: Success

|
On the other hand, when i type 'startxcfe4' (after having stopped xdm), XFCE starts without complaint. When i switch back to the console (Ctr-Alt-F1) i see | Code: | | (polkit-gnome-authentication-agent-1:4465):polkit-gnome-1-WARNING **: Unable to determine the session we are in: GDBus.Error:org.freedesktop.ConsoleKit.Manager.Error.General: Uable to lookup session information for process '4465' |
Any idea why this happens and how this can be fixed?
Thanks
Jody

@fedeliallalinea: thank you that helped a bit.
Indeed my .Xauthority had wrong permissions. I changed that and now loghtdm is not restarted when i log in.
However, neither is xfce started - after log in i see some strange borderless windows (some of them seem to be terminals).
Now i have to find out why xfce is not started... |

What are the contents of /etc/lightdm/lightdm.conf, excluding comments?:
| Code: | | grep -v ^# /etc/lightdm/lightdm.conf |
Also, what files do you have in that directory?:
| Code: | | ls -la /etc/lightdm |

Hi Fitzcarraldo
/etc/lightdm/lightdm.conf: | Code: | [LightDM]
session-wrapper=/etc/lightdm/Xsession
[Seat:*]
session-wrapper=/etc/lightdm/Xsession
[XDMCPServer]
[VNCServer] |
/etc/lightdm: | Code: | drwxr-xr-x 2 root root 4096 Aug 23 15:51 .
drwxr-xr-x 69 root root 4096 Aug 25 10:32 ..
-rw-r--r-- 1 root root 40 Aug 23 15:51 keys.conf
-rw-r--r-- 1 root root 6710 Aug 23 15:51 lightdm.conf
-rw-r--r-- 1 root root 698 Aug 23 15:51 lightdm-gtk-greeter.conf
-rw-r--r-- 1 root root 453 Aug 23 15:51 users.conf
-rwxr-xr-x 1 root root 1819 Aug 23 15:51 Xsession |
I have not been able to find out how Lightdm is supposed to know about xfce4's existence, can you elucidate?
Thanks
Jody |

In the top right of the Lightdm window, you have an icon you can click on who allow you to select the desktop environment or the window manager you want from the ones who are installed. This icon have the logo of the one who is selected. You need to set the appropriate choice for you before login.
