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.

Comment 1 Tomas Pelka 2011-11-02 10:33:22 UTC
Ben I think this is well known DP problem, nouveau didn't ever work with DP correctly, right?

Comment 3 Trond H. Amundsen 2011-12-08 19:27:40 UTC
I have this problem as well. Same card, DP, system running rhel6.2:

  xorg-x11-drv-nouveau-0.0.16-13.20110719gitde9d1ba.el6.x86_64
  kernel-2.6.32-220.el6.x86_64

The problem is really in the kernel driver. Previous kernels from 6.1 and 6.0 works fine, so this is a regression.

The component for this bug should be changed to kernel.

Comment 8 Tomas Pelka 2012-05-22 08:33:00 UTC
OK, without adapter it is working just fine. That is weird since I hadn't problems with other graphics (nVidia and ATI).

Comment 10 Suzanne Logcher 2012-05-29 19:36:05 UTC
This request was evaluated by Red Hat Product Management for inclusion in the
current release of Red Hat Enterprise Linux. Because the affected component is
not scheduled to be updated in the current release, Red Hat is unfortunately
unable to address this request at this time.  It has been proposed for the next
release.

I have noticed similar problem with Quadro FX 3700 adapter with RHEL 6.2 with 24" FP display. It looks like system boots up but no display (blank FP display). But when I connected a smaller FP display, system boots up the and display image is 1680x1050 @60Hz, which is perfect. Here I allowed default (enabled) Nouveau video driver/module. 

But it failed to give any display with preset resolution, 1920x1680 @60Hz. Could this be a bug with Nouveau package?
