Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

Filed from caserun https://tcms.engineering.redhat.com/run/99313/#caserun_3816197
Version-Release number of selected component (if applicable):
Build : RHEL-7.0-20131111.1
xorg-x11-server-Xorg-1.14.99.901-5.20131101.el7.x86_64
xorg-x11-drv-ati-7.2.0-6.20131023gitf1dc677.el7.x86_64
kernel-3.10.0-48.el7.x86_64
Steps to Reproduce:
1. connect a monitor to your machine
2. boot up the machine
3. log into GNOME or KDE
1. disconnect the monitor
2. plug in another one instead
Actual results:
Hotplugging results in sleeping monitor most of the time. A few time the screen lit black, but this caused it to hang.
Expected results:
Screen should be correectly powered on with a native resolution
This need to be retested but here i can not reproduce with :
linux-firmware-20140102-0.2.git52d77db.el7.noarch
kernel-3.10.0-89
mesa-dri-drivers-9.2.5
xorg-x11-drv-ati-7.2.0-8.20140113git3213df1
xorg-x11-glamor-0.5.1-4.20140115gitfb4d046c
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.

RHEL-7.2-20150820.0
xorg-x11-server-Xorg-1.17.2-7.el7.x86_64
xorg-x11-drv-ati-7.5.0-3.el7.x86_64
kernel-3.10.0-306.0.1.el7.x86_64
linux-firmware-20150727-41.git75cc3ef.el7.noarch
mesa-dri-drivers-10.6.0-1.20150616.el7.x86_64
Hotplugging mostly works with some issues:
1. Machine will reboot immediately if DP was not plugged on boot, and gets plugged [1]
2. Machine will reboot immediately if DVI-I port is disconnected (at least when using analog connection)

xorg-x11-drv-ati-7.5.0-3.el7.x86_64
kernel-3.10.0-306.0.1.el7.x86_64

Most likely problem was lack of a ground connection on the backing plate.
