Failed to run action "Log Out"

DavidBiesack · 2013-07-17 21:37:48

I downloaded, built, and installed xfce4 4.10 (PREFIX=/local) and am running xfce4-panel (system is Xubuntu 13.04, running lightdm. I login with either an xubuntu or xfce session). I added the action buttons to my panel, but the logout button causes this dialog:

The name org.xfce.SessionManager was
not provided by any .service files

and logging out fails. I can't find a root cause. xfce4-panel preferences confirms I'm running 4.10

(I've reverted to killing my .xinit to logout, but I'd rather get standard logout and related display manager handlers so I can gracefully shutdown virtualbox virtual machines etc. at logout).

What causes this, and how to fix?

Out of curiosity, why did you build Xfce 4.10? Xubuntu 13.04 comes wilth Xfce 4.10 bundled in.

I was having the problem and I checked the --version on something and I thought I had an older version. I can't remember which tool it was, tho. I had the problem before I built it, tho (that was one of the reasons I built it, as it appeared I had an older install). But the /usr/bin/xfce4-* apps all report 4.10 or 4.10.2 now, so my xubuntu system is "up to date".

What .service file is missing? I'm not very familiar with X session management and these .service files.

Is xfce4-session running?

ps -ef  |grep xfce4-session

Are there any messages in ~/.xsession-errors related to this?

Did the logout work before you built Xfce?

DavidBiesack · 2013-07-23 17:13:27

no, it is not running

ps -ef  |grep xfce4-session
sasdjb   22645 22626  0 12:56 pts/0    00:00:00 grep xfce4-session

my .xsession-errors shows

(xfdesktop:19757): GLib-WARNING **: (/build/buildd/glib2.0-2.36.0/./glib/gerror.c:390):g_error_new_valist: runtime check failed: (domain != 0)

Here is my lightdm log, if that helps:

You need to have xfce4-session running. Is it installed?

apt-cache policy xfce4-session

Is it possible that another session manager is running?

ps -ef | grep session

And finally, does it help if you clear out your sessions cache? The best way to do this is to log out of the GUI, go to the first tty (Ctrl+Alt+F1), log in to the text console, then:

cd $HOME/.cache
rm -rf sessions

...be extra careful with the "rm -rf" command.

Then Ctrl+Alt+F7 and log back in to the GUI and test.
