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.

Created attachment 1514189 [details]
xorg.conf.d file that enables ctrl+alt+backspace

Description of problem: 
After configuring Ctrl+Alt+Backspace to restart the X server, if you are at the GDM login screen it will terminate X instead of restarting X. The only way to resolve this issue is to login and do "sudo systemctl restart gdm"

Version-Release number of selected component (if applicable):
gdm-3.28.2-10.el7


How reproducible: If you have Ctrl+Alt+Backspace configured correctly, you can use it from GNOME or KDE to bring you back to the GDM login screen, but if you perform this action from GDM it will kill the X server but GDM will continue to be running.


Steps to Reproduce:
1. Copy the attached file into /etc/X11/xorg.conf.d/
2. Restart GDM
3. After you are at GDM, press Ctrl+Alt+Backspace to attempt to restart the X server, you will be presented with a black screen in which X will terminate.

Actual results:
the X server will crash and not automatically restart.

Expected results:
the X server will restart and you will be back at the GDM login screen.

Additional info:
