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_3816195

Version-Release number of selected component (if applicable):
RHEL-7.0-20131111.1Build : 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: 
Get your display highest supported resolution, use xrandr for example (it is
the first resolution in the list, 1650x1050 in my case).

 


 1. Run xrandr and set higher resolution that you have supported

    xrandr  --output LVDS --panning 1600x1200


Note: replace "LVDS" with real name of your output interface.

 



Actual results: 
Panning works fine but when returning to native res there is severe screen corruption. Panning and un-panning again (by feel) just makes it worse..

Expected results:
Make sure the screen is panned and you can tavel in panned space. No crashes/
errors at display should appear.

You need linux-firmware >= 20131106-0.1.git7d0c7a8

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

We believe this is already fixed but moving to 7.1

This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.

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
