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.

Red Hat Product Errata RHSA-2015:2152 0 normal SHIPPED_LIVE Important: kernel security, bug fix, and enhancement update 2015-11-20 00:56:02 UTC

Description Vasiliy Sharapov 2013-11-24 09:57:35 UTC
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

Comment 2 Jérôme Glisse 2013-12-10 21:39:04 UTC
You need linux-firmware >= 20131106-0.1.git7d0c7a8

Comment 3 Jérôme Glisse 2014-02-20 20:50:17 UTC
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

Comment 4 Jérôme Glisse 2014-03-07 15:27:17 UTC
We believe this is already fixed but moving to 7.1

Comment 6 Jérôme Glisse 2014-07-17 15:19:33 UTC
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.

Comment 12 Vasiliy Sharapov 2015-09-16 18:03:42 UTC
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)

[1]: There is already a bug for this: https://bugzilla.redhat.com/show_bug.cgi?id=1263788

Comment 13 Vasiliy Sharapov 2015-09-23 11:31:04 UTC
Retested with a different case.

Verified fixed in:
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

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