Description Henrique Martins 2010-05-26 06:24:47 UTC

Description of problem:
yum upgraded to F13, no apparent problems but I don't have a login box.  New background is there, bottom bar with off button displays, but instead of a login box I have a one to two pixel vertical with line in the middle of the screen, as tall as probably the login box used to be.

Also telinit 3 from the Alt-Fx console yields an error message claiming that the greeter is still running, clicking on the box/accepting the error makes it go away but X never dies until I kill it.

Using xdm meanwhile

Version-Release number of selected component (if applicable):
gdm-2.30.2-1.fc13.i686

How reproducible:
always

Steps to Reproduce:
1. reboot, wait for login screen
2.
3.
  
Actual results:
No login box

Expected results:
Login box

Additional info:
F12 had user list and sound disabled for the greeter, not sure if that makes a difference

Comment 1 Henrique Martins 2010-05-26 14:01:52 UTC

Debugged this this morning and culprit is gdm/simple-greeter with disable_user_list set to true.

If I set the value of that option to true in
  /etc/gconf/gconf.xml.mandatory/apps/gdm/simple-greeter/%gconf.xml
as in

<?xml version="1.0"?>
<gconf>
  <entry name="disable_user_list" mtime="1263745615" type="bool" value="true"/>
</gconf>

and telinit 3/telinit 5 to restart gdm, the simple-greeter login box is a single vertical line, mostly one pixel wide, with a couple of 2 pixel wide sections.

If I change the file to have value="false", the default, and restart gdm again, the login box is back to normal, albeit with the user list I don't want to see.

Reproduced it twice, so it seems symptomatic.

Comment 2 Roy Rankin 2010-05-28 03:29:05 UTC

I have the same issue with disable_user_list set to true after preupgrade FC12->FC13

Comment 3 John Heidemann 2010-05-28 20:54:38 UTC

This bug is a show-stopper on F13 with disable_user_list set to true.

gdm is crashing and the process table fills up processes that contain "pam" and "gdm" on the command line.  In a few minutes these processes bring the system to a crawl, preventing logins over the network or from another virtual console.

Some relevant lines from /var/log/messages:

Comment 4 John Heidemann 2010-05-28 20:56:25 UTC

Continuing comment #3

work-around is the usual: give-up on gdm and switch to kdm (via DISPLAYMANAGER=KDE in /etc/sysconfig/desktop), or turn off disable_user_list

Also, given that this bricks a system without work-around, perhaps severity should be high.
