Description Nicholas, Crawford 2014-10-26 19:20:58 UTC

Description of problem:
With disable-user-list set when a banner is properly set and displayed, once the screen blanks and locks the banner is lost.

Without disable-user-list the banner is displayed normally only once a user is selected or 'Not listed?' is selected. Contrasted with disable-user-list where the banner is displayed on the initial screen.

Version-Release number of selected component (if applicable):
gdm-3.8.4-28.el7_0.1.x86_64

How reproducible:
100%

Steps to Reproduce:
1. create dconf rules to disable the user-list and display a banner, also lower session idle to aide in debugging

# echo -e "[org/gnome/desktop/session]\nidle-delay=uint32 15\n\n[org/gnome/login-screen]\ndisable-user-list=true\nbanner-message-enable=true\nbanner-message-text=\"This is a banner\"\n" > /etc/dconf/db/site.d/00-test
# echo -e "/org/gnome/desktop/session/idle-delay\n/org/gnome/login-screen/disable-user-list\n/org/gnome/login-screen/banner-message-enable\n/org/gnome/login-screen/banner-message-text" > /etc/dconf/db/site.d/locks/00-test-locks
# dconf update

2. Reboot, notice the banner displayed on the login screen
3. Allow the screen to blank
4. Wake the login screen and notice the banner is now gone

Actual results:
Banner is lost when login screen blanks.

Expected results:
Banner is displayed when login screen returns from lock/blank.

Additional info:
Work-around: setting idle-delay to "uint32 0" for gdm and preventing the screen from blanking allows the user to login normally. However, the screen appears to never blank nor go to sleep.

Unfortunately, disabling idle-activation-enabled and lock-enabled appear to have no affect on this bug.

Comment 3 Nicholas, Crawford 2014-10-27 04:14:44 UTC

Apologies,

The original report includes an error from a careless cut'n'paste.

in Work-around;

"setting idle-delay to "uint32 0" for gdm and preventing the screen  from blanking allows the user to login normally."

Should read;

"setting idle-delay to "uint32 0" for gdm prevents the screen from blanking and guarantees the banner will continue to display."
