After upgrade to lightdm 1.7.7 I can't mount external disks or shutdown the system from the XFCE desktop. As far as I could find out this is because lightdm doesn't create an active consolekit session therefore authentication for priviledged actions fails. I went back to lightdm 1.4.0-r2 and the problem was gone. Reproducible: Always Steps to Reproduce: 1. upgrade to lightdm 1.7.7 2. restart lightdm 3. login and try to mount a USB disk or shutdown the system Actual Results: I get "not authorized" for the mount attempt. The button for system shutdown is grey. Expected Results: mounted disk coloured and working shutdown button I've run a complete system upgrade (-uDN) when I came across this bug. I reverted all changes in consolekit, pam, dbus and what else could have been involved config files: emerge --noconfmem consolekit pambase shadow sys-fs/udisks sys-power/upower xfce-base/xfce4-session sys-auth/polkit gnome-extra/polkit-gnome udev xfce-base/xfdesktop But that didn't help either.

I have the similar problems, but my desktop is KDE. Using kdm as login manager solves all the problems.
Same here. I think lightdm might require systemd-logind instead of ConsoleKit now...
(In reply to Mads from comment #6) > Same here. I think lightdm might require systemd-logind instead of > ConsoleKit now... I know that lightdm got some support for systemd in version 1.7.0 (2 months ago) but I would be surprised if they immediately removed consolekit support. Also I don't see a logind ebuild (it doesn't depend on systemd afaik) and the lightdm ebuild doesn't have a systemd dependency.
I have now done some regression testing and this bug was introduced with lightdm 1.7.5. Version 1.7.4 is the last one that works correctly (I also checked with the latest 1.7.9 and it is still there). Running a diff over the 2 versions shows that there have been a lot of changes in the session handling code.
Probably worth taking it upstream then, 1.7.5 did come out with "This release contains a quite major refactoring so please look out for any regressions" after all
Yes please someone needs to take this upstream.

I could finally found a solution. I hope it works for you too. Also, I don't use neither udev, eudev nor systemd and I don't use a conventional Gentoo environment. But it worth trying.

I tested starting /etc/init.d/consolekit before lightdm at version 1.7.7, and that didn't work... does this mean that there has been some fixing between 1.7.7 and 1.7.9, or does Jimmy.Jazz do something special that I haven't grasped yet?

Do you mean you did: root@bla # /etc/init.d/consolekit start root@bla # openvt -c 7 -- /usr/sbin/lightdm For me that works with 1.7.4, 1.7.7 and 1.7.9 (didn't try other versions). Of course I had consolekit already running (so no need for the first command) and had to stop /etc/init.d/xdm before running the second.
(In reply to Jimmy.Jazz from comment #12) > : lightdm since x11-misc/lightdm-1.7.9 needs a valid allocated tty to work > on. > : most often /dev/tty7 is used for X. I have to admit that I have no idea how lightdm (or any other DM) knows which terminal to use. I guess tty7 has just established itself as a default that is used if nothing else is configured. > : run consolekit daemon before lightdm otherwise dbus will run it on tty0 and > : will lock the tty7 until you manually kill consolekit daemon. Not sure I get that. I see the lightdm greeter on tty7 and the opened session is also there. There is a change in lightdm-1.7.5 that is supposed to allow greeter and session to run on different display servers. But from my perspective both run on the same just as usual for a simple desktop system. So it "forgets" to inform consolekit that the created session is running on tty7. Or it just puts in the wrong value. x11-display = ':0' x11-display-device = ':0' <--- This looks just like the x11-display and should be '/dev/tty7'
1.6.0 seems to be fixing the problem to me. I will bring this to portage for us who don't use systemd.
1.6.x also works for me, 1.7.x breaks ck session
Created attachment 358890 [details, diff] proposed patch We're up to lightdm-1.7.15 now in gentoo, which still has the same bug, but this patch seems to fix it for me. $ ck-list-sessions Session6: unix-user = '1000' realname = 'Ian Abbott' seat = 'Seat1' session-type = '' active = TRUE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2013-09-17T18:09:45.380194Z' login-session-id = '4'

I'd rather avoid carrying this patch in Gentoo forever. For now, those that have this problem can use the 1.6.X ebuild?

So far they haven't even confirmed that they have a bug. And I fear that they are so focused on systemd that they won't even look at the bug report. :-( So for now I'll stick to the 1.6.

This is now fixed upstream in lightdm-1.7.16. (Though I haven't tested it yet, my one-line change has been committed.)
(In reply to Ian Abbott from comment #22) > This is now fixed upstream in lightdm-1.7.16. (Though I haven't tested it > yet, my one-line change has been committed.) Wow that was fast! I just gave 1.7.16 a try and it works. Now the 1.7.16 ebuild just needs to hit the tree to make it official. Thanks for debugging it and getting upstream to take the fix.
x11-misc/lightdm-1.7.16 is now in the tree.
Awesome work. Thank you Ian for providing a fix and for pushing it upstream!
I am using lightdm-1.10.3 and encountered exactly the same Problems Robert described on the initial post. I assume my xfce4 is started with "exec ck-launch-session startxfce4" (line from /etcX11/Sessions/Xsession) I seem to have several consolekit sessions (right after startup): ----- $ ck-list-sessions Session3: unix-user = '1010' realname = '(null)' seat = 'Seat1' session-type = '' active = FALSE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2015-02-02T15:30:48.994016Z' login-session-id = '2' Session4: unix-user = '1010' realname = '(null)' seat = 'Seat1' session-type = '' active = FALSE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2015-02-02T15:30:49.192362Z' login-session-id = '2' Session2: unix-user = '1010' realname = '(null)' seat = 'Seat1' session-type = '' active = TRUE x11-display = ':0' x11-display-device = '/dev/tty7' display-device = '' remote-host-name = '' is-local = TRUE on-since = '2015-02-02T15:30:48.658358Z' login-session-id = '2' ----- /var/log/lightdm/lightdm.log contains various warnings related to consolekit Going back to lightdm-1.8.5 didn't help either
jody, you have a different issue. You do have an active session (Session2) but 2 more sessions on the same display. Also there is something wrong with your /etc/X11/Sessions/Xsession because it doesn't contain "exec ck-launch-session startxfce4" unless you put it there. What I think might be the problem is that you have set lightdm to start Xsession instead of Xfce. I use the default GTK greeter and there the button to change that is the one in the upper right screen corner, left of the accessability button. Please check that. Also make sure that /etc/X11/Sessions/Xfce4 (or /etc/X11/Sessions/Xfce) only contains "startxfce4", no exec or ck-launch-session.
LightDM creates its own ConsoleKit session, so jody's configuration is trying to create a nested ConsoleKit session - something which won't work! Interestingly, the LightDM developers removed ConsoleKit support sometime after LightDM development release 1.13.0 and reinstated it a couple of days later (so it's back in release 1.13.1). Although the original ConsoleKit is pretty much abandoned, it was forked by an XFCE developer and the fork is alive and well. http://lists.freedesktop.org/archives/lightdm/2014-November/000731.html
Guys this is an old bug. If this is not a bug but rather a user-side problem please take it to the forums or gentoo-user @ ML. If this is indeed a bug, you need to open a new after after you have tried the latest ~testing or even masked version of lightdm and we will see what to do.
