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. Additional info:

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. *** This bug has been marked as a duplicate of bug 606808 ***
