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.

Add regression keyword according to this.
Comment 4 qge 2014-08-29 06:05:49 UTC 
works well with 
xorg-x11-server-Xorg-1.15.0-16.el6 & xorg-x11-drv-fbdev-0.4.3-15-el6
does not work with
xorg-x11-server-Xorg-1.15.0-18.el6 & xorg-x11-drv-fbdev-0.4.3-16-el6

Hi Adam,

It happened on the RHEL6.6 running as Hyper-V guest. If needed, we Virt-QE would like to setup related ENV for you.
It is an important and urgent issue. With the bug, our customers will no use the GUI at all.
Could you help to have a look at the issue? Could i know you plan about it? 

Thanks,

Hi Tomas,

This is a regression problem. It works well on xorg-x11-server-Xorg-1.15.0-16.el6, while it does not work on xorg-x11-server-Xorg-1.15.0-18.el6.

The bug 1127104 is fixed on xorg-x11-server-1.15.0-17.el6. In my opinion, it is not a duplicate of bug 1127104.

Could you please help to have a look at the issue? We'd like to setup test ENV for you.

Oh I see, sorry.

But please set up the env.
