RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Gary Gatling 2010-07-01 19:48:57 UTC 
Description of problem:
In RHEL 6 beta 2, you cannot set the 
gdm display manager to use the key disable_user_list as true.

When this key is set to true, the login window is only
1 pixel wide and you can't login.

Version-Release number of selected component (if applicable):

RHEL 6 beta 2. i386 and x86_64 bit versions of workstation were tested.

Happens either with open source video drivers or the ones from NVIDIA.

How reproducible:

install RHEL 6 beta 2 workstation. (Either 32 bit or 64 bit)

run this command as root:

gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults
 --type bool --set /apps/gdm/simple-greeter/disable_user_list true

log out or reboot.

Notice the the login window is only 1 pixel wide. Thus, you cannot login.

Steps to Reproduce:
1. install RHEL 6 beta 2.
2. run gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults
 --type bool --set /apps/gdm/simple-greeter/disable_user_list true
3. logout and observe login window.
  
Actual results: a gdm window 1 pixel wide you can't type into or log in with.

Expected results:

a gdm window where a user can type "Username" into a text box.

Comment 4 Gary Gatling 2010-07-12 17:22:49 UTC 
I think this bug is different from bug 606808, because when I run this command as root:

gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --type bool --set /apps/gdm/simple-greeter/disable_user_list true

The gdm log in window becomes only 1 pixel wide. So the command is having some
effect. Just not the desired one. Instead of showing a username text box it collapses the whole window so that it is only one pixel wide. This one
pixel wide thing (window?) also blinks on and off. Like once per second.

There is no way to log in once this happens because there is no where to type your username or to select the user from a long list. Clicking on the one
pixel wide thing doesn't have any effect. There are no widgets. No boxes, nothing
but a vertical blinking line.

Running the above command as root worked on RHEL 6 beta 1. Its broken in RHEL 6 beta 2. The version of the gdm rpm in beta 2 is: 2.30.2-3.el6

I am not trying to run this command as a regular user. I am running this command
as root. (In a %post script of an installing rpm)

Thanks

Hi Gary,

The bug you described is what was fixed.  bug 606808 did have a bit of confusion in it regarding how to set disable_user_list, but that's the bug we've been using as the "master" issue for the problem you've described with the blinking thin vertical window.
