My system is refusing to allow me to log out from my gnome session when I click the "Log Out" button. I can log in just fine, and the session appears to work okay. However, when I attempt to log out (or type "gnome-session-quit" at a terminal), I am ultimately brought back to a fresh session.
UPDATE: Eventually, the system will let me log out, but I have to log out four times. lightdm --session-child
appears to be spawned multiple times, but once it has been cleared, I can log out.
UPDATE 2: Added some information from the syslog, showing that dbus is rejecting "ReleaseSession" from the lightdm --session-child
process. I think this has to be some kind of permission thing, but I'm not sure where to look or how to reset it.
I am running 16.04.5 LTS, kernel 4.4.0-130-generic, and I have the nvidia-384 drivers installed.
Some notes:
- Open applications are closed, and the Unity/Gnome display goes away after a confirm that I want to log out. I'm left with a desktop background for a few seconds, then the Unity/Gnome interface pops up again, just like I had started a new session.
- This behavior occurs when I use both Gnome (gnome.desktop) and Ubuntu/Unity (ubuntu.desktop) sessions.
- The behavior does not occur when I use gdm3, only lightdm.
- I have tried cleaning out lightdm, removing the contents of /var/lightdm, and resetting the files in /etc/lightdm. I've uninstalled and reinstalled lightdm as well as tried
dpkg-reconfigure lightdm
. No luck. - The problem occurs for old users as well as newly-created users.
- The behavior is the same using the "nvidia-340" drivers.
- I have also attempted uninstalling and reinstalling xinit and gnome to no avail. Again, the session lets me log in, but I can't seem to log out.
- Unfortunately, I'm not quite sure when the behavior started, so I can't trace it to a particular update or system change. Certainly within the past two months.
I'm not exactly sure where to start with the logs. However, I've included the results from /var/log/lightdm
.
Thanks in advance for any help.
UPDATE 2: Here are the entries from syslog. There a quite a few of these:
dbus: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.121" (uid=1046 pid=3079 comm="lightdm --session-child 12 19 ") interface="org.freedesktop.login1.Manager" member="ReleaseSession" error name="(unset)" requested_reply="0" destination="org.freedesktop.login1" (uid=0 pid=1148 comm="/lib/systemd/systemd-logind "): 1 Time(s) dbus: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.126" (uid=1046 pid=2640 comm="lightdm --session-child 12 19 ") interface="org.freedesktop.login1.Manager" member="ReleaseSession" error name="(unset)" requested_reply="0" destination="org.freedesktop.login1" (uid=0 pid=1142 comm="/lib/systemd/systemd-logind "): 1 Time(s)
UPDATE: As mentioned above, lightdm appears to span multiple lightdm --session-child
processes. I have a similar system that behaves normally. On that system, after login, only one process exists after login, and it is owned by root (for the greeter?). On my system, two lightdm --session-child
processes exist after login, and are owned by the user. See below for a freshly-created user (fresh):
Session-child processes before login:
root 1530 1442 0 11:03 ? 00:00:00 lightdm --session-child 16 19 root 1647 1442 0 11:03 ? 00:00:00 lightdm --session-child 12 19
Session-child processes after the first login:
root 1647 1442 0 11:03 ? 00:00:00 lightdm --session-child 12 19 fresh 3109 1647 0 11:04 ? 00:00:00 lightdm --session-child 12 19 fresh 3110 3109 0 11:04 ? 00:00:00 lightdm --session-child 12 19
Session-child processes after the first logout attempt:
root 1647 1442 0 11:03 ? 00:00:00 lightdm --session-child 12 19 fresh 3109 1647 0 11:04 ? 00:00:00 lightdm --session-child 12 19
Session-child processes after the second logout attempt:
root 1647 1442 0 11:03 ? 00:00:00 lightdm --session-child 12 19 fresh 4470 1647 0 11:06 ? 00:00:00 lightdm --session-child 12 19
Session-child processes after the third logout attempt. On a normal system, a single session-child process, owned by root, is the typical result after the user logs in. On my system, I have to log out three times to get down to this point:
root 1647 1442 0 11:03 ? 00:00:00 lightdm --session-child 12 19
Session-child processes after the fourth logout attempt (a successful logout):
root 5723 1442 0 11:08 ? 00:00:00 lightdm --session-child 16 19 root 5775 1442 0 11:08 ? 00:00:00 lightdm --session-child 12 19
I have no idea why so many of these processes are being spawned, or why they refuse to die. Worse, I have no idea where to look for what might be causing the hangup. I see nothing obvious in the lightdm logs.
