Cannot shutdown via UI

[Michael Nelson]

STR: Click on the top-right menu widget and select 'Shut Down...'
ER: machine shuts down
AR: I'm logged out and returned to the lightdm screen. Selecting Shut down from the menu there brings up a confirmation dialog, but confirming that leaves the system unchanged (ie. on the lightdm screen).

Note: I then tried switching to a tty and doing `sudo shutdown 0` which started shutting down, but dropped me to a root prompt. Details: http://paste.ubuntu.com/705461/

Upstart bug split out to new bug 871860.

[James Hunt (jamesodhunt)]

The primary issue here I think is not with Upstart but with gnome/unity.

[James Hunt (jamesodhunt)]

Menu logout issues appear to be a unity issue.

[Launchpad Janitor (janitor)]

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

thank you for your bug report, could you switch to a vt and type "ck-list-sessions > log" when you get the issue and add log to the bug?

[Dmitry Shachnev (mitya57)]

Huh, I'm able to reproduce it!

Do you have PPA version of liboverlay-scrollbar installed?

[Lazlo (lazlo-deactivatedaccount)]

No, I have not installed liboverlay-scrollbar.

[Dmitry Shachnev (mitya57)]

What I get is definitely related to liboverlay-scrollbar.

Can you please reproduce this bug, login and attach here:
- Your ~/.xsession-errors and ~/.xsession-errors.old (these are hidden files)
- Output of "dmesg" command

[Dmitry Shachnev (mitya57)]

Thanks!
Unfortunately, these files don't contain any information about gnome-session crash, as mine do.

I will continue my investigations.

[Lazlo (lazlo-deactivatedaccount)]

I think this bug is caused by Unity starting 2 sessions as seen in #10. May be causing other bugs.

[Lazlo (lazlo-deactivatedaccount)]

My /etc/lightdm/lightdm.conf contained autologin-user=<user>.

Commenting out this line solved this issue for me. Autologin was not active - I had to login with password, and I never selected autologin.

[Helipilot (huckleberry)]

Thanks, Lazlo, that worked! :)

[Fernando Sancho (toptnc)]

I have solved it by adding "acpi=force" to boot options in grub.
