switch user in the KDE menu shows logged out users

[Albert Bogdanowicz]

After logging out from terminal session (CTRL+ALT+F*) I still see that I can switch to that terminal as that user. The problem is only in the KDE menu, logging out is correct (the only process on that tty is getty).

[Brian Murray (brian-murray)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. I can confirm that this is a problem with with kdm version 3.5.6-0ubuntu12 on Feisty Fawn.

[Brian Murray (brian-murray)]

Version: 3.5.6-0ubuntu13 (using KDE KDE 3.5.6)
Installed from: Ubuntu Packages
OS: Linux

After logging into and out of a terminal session (a TTY login vt[1-4]) the user still seems to be logged in when you go to the "Switch users" menu. This bug was originally reported in Malone - Ubuntu's bug tracker and can be viewed at https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/73025 by Albert Bogdanowicz. I have also reproduced this bug and can provide any additional information if required.

[Oswald Buddenhagen (ossi-kde)]

please run "who -a" before, during and after somebody is logged in on tty* the first time. post the first complete and "diff -u" first->second and second->third. note: start as few terminals as possible before you do it.

uhm ... just to make sure: the first one is from before you could see the problem, yes? the uptime doesn't exactly suggest this.
anyway, there seem to be no dead entries left behind, unless who applies a different interpretation than kdm.
try ssh localhost. that login should also appear in who output and in the shutdown warning list. and it should disappear after logout, of course.
are you aware of ubuntu-/debian-specific kdm-patches to the kdm backend?

[Brian Murray (brian-murray)]

Here is the information you requested again after rebooting so the first log should be clean i.e. before any user had logged in on tty[1-4].

[Oswald Buddenhagen (ossi-kde)]

nothing unusual about it ...

is there a difference between
1) tty login - show kdm session list - tty logout - show kdm session list
and
2) tty login - tty logout - show kdm session list
?

[Oswald Buddenhagen (ossi-kde)]

ping!

[Oswald Buddenhagen (ossi-kde)]

based on the fact that i got no new information and it just works for me, i am forced to close this.

[Brian Murray (brian-murray)]

Still an issue with Gutsy Gibbon using kdm version 3.5.7-1ubuntu8.

[Brian Murray (brian-murray)]

In regards to Comment #5 - No there is not a difference between the two things. I also do not know of any ubuntu or debian specific patches to kdm. I am also able to reproduce this using kdm version 3.5.7-1ubuntu8. What other steps could I take to help troubleshoot this?

[Oswald Buddenhagen (ossi-kde)]

i assume you did the tests immediately after a reboot, as usual.
i have no idea what else i could request from you save investigating this yourself in gdb - i could provide some assistance, but you need to know what you're doing ...

Related to https://bugs.edge.launchpad.net/upstart/+bug/183729, possibly?

Still applicable for Intrepid.

[Albert Astals Cid (aacid)]

Reopening, i can reproduce it on:
 KUbuntu 9.04 with binary packages of KDE 4.2.3
 KUbuntu 9.04 with self compiled KDE trunk
 Fedora 10 with binary packages of KDE 4.2.2

kdmctl list shows that after login in and login out in a virtual terminal there are no changes and kcm thinks we are still logged in.

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. But don't worry! This issue is being tracked by the KDE developers at: http://bugs.kde.org/show_bug.cgi?id=142615
Once fixed in KDE, it will be included in Kubuntu once the KDE version the fix is in in reaches Kubuntu.

Thanks!
