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 of problem:

The banner message is displayed in two different places depending on the resolution.

Location 2: Banner message is above the user/pass text entry box. And the user/pass text entry box is centred on the screen. (1440x900, 1680x1050)



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

$ rpm -qa gdm
gdm-3.8.4-32.el7.x86_64


How reproducible:
Always


Steps to Reproduce:
$ create /etc/dconf/db/gdm.d/01_banner (see attached)

Comment 3 Matthew Gyurgyik 2015-04-29 16:52:38 UTC 
Errata RHSA-2015-0535 states "* Prior to this update, only a small area was available on the GDM login screen for a custom text banner. As a consequence, when a long banner was used, it did not fit into the area, and the person reading the banner had to use scrollbars to view the whole text. With this update, more space is used for the banner if necessary, which allows the user to read the message conveniently. (BZ#1110036)"

It sound like this change may be related to this problem. Sadly, BZ#1110036 is private and I can not view it.
Comment 5 Ray Strode [halfline] 2015-05-04 14:56:11 UTC 
Hi, showing two different layouts depending on screen resolution and message length is actually "by design".  The idea is to only show short messages above, and show long messages on the side.

Clearly, in your case, the message should be on the side in both situations, though.
Comment 7 Michal Domonkos 2015-05-11 16:25:01 UTC 
It looks like this wasn't fixed in GNOME-3.14 in its entirety.

Now the text seems to never overflow any more, however, it's always placed on top of the user list, spanning the whole screen horizontally and that doesn't seem to change with the resolution either (screenshot attached).

Comment 9 Michal Domonkos 2015-06-02 09:47:20 UTC 
On GNOME-3.16 (Fedora 22), I no longer see the issue I had in comment 7.  The banner always sticks to the side of the user list as it should.
