Bug 273386 – gnome-base/gdm-2.20.9-r1: wrong update utmp and wtmp

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Kazankov Alexander 2009-06-09 16:44:40 UTC]

I have WM-fluxbox-1.1.1. When XDMCP is enabled in gdm, and multiple users log in, it appears that only the latest user is shown when doing a user listing with the w, who or users command.  The output of 'last' is correct though.


Reproducible: Always

Steps to Reproduce:
1. Enable XDMCP
2. Log in 2 users
3. type w


Actual Results:  
Only the last user to log in is shown


Expected Results:  
All users logged in should be shown

please try with gdm-2.20.10-r1 and pambase-20090515 (it works just fine here, it even lists open terminals)

[Comment 2 Kazankov Alexander 2009-06-15 06:23:12 UTC]

I have already tried such variant, but without updating pambase. The result was the same. I do not think that if to update pambase, something to change.

The result of registration with sessreg differs from built-in in gdm: each user has unique id lines. In a case with gdm it always same. The code does not differ at 2.20.10 from 2.20.9!

I have made a patch and I think today to me it will be possible to check up it.

GDM custom config

Forget about that.

[Comment 4 Gilles Dartiguelongue (RETIRED) 2009-06-15 14:24:13 UTC]

So you need to have those Utmp lines to make it work ? There is something really wrong in your setup I believe.

[Comment 5 Balint Dobai-Pataky 2009-07-17 12:46:35 UTC]

thanks for the utmp lines, it did it for me.

UTMP fix

With that fix I have working gdm.

[Comment 7 Gilles Dartiguelongue (RETIRED) 2009-07-23 21:14:08 UTC]

Could you report this upstream (at bugs.gnome.org) to see what they think about this patch ?

[Comment 8 Gilles Dartiguelongue (RETIRED) 2009-08-02 19:50:07 UTC]

Could you guys paste the output of ls -l /var/run/utmp ?
