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.

Description Matthias Schroder 2010-04-29 16:51:50 UTC 
Description of problem: The intel driver does not see the second screen, and thus does not allow dual screen setup


Version-Release number of selected component (if applicable): 2.10.0-4.el6.i686


How reproducible: 100%


Steps to Reproduce:
1. connect two screens
2. start x
3. check Xorg.0.log or do 'xrandr -q'
  
Actual results: Only screen connected via VGA is seen and used


Expected results: Both screens are seen and can be used


Additional info: This is an HP7900 with 00:02.1 Display controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03)

This looks bad as well
Comment 9 Matthias Schroder 2010-04-30 07:41:09 UTC 
Concerning pam_krb5: I did an install with package groups 'base' 'desktop' 'X11' and 'Fonts' only, and pam_krb5 is not part of any of these sets. But I don't believe that adding it has an impact on the intel driver ;)

I haven't tried to blame crashing Xorg on missing pam_krb5, just wasn't sure whether it isn't a factor. Leaving this to developers for further analysis.
Comment 11 Adam Jackson 2010-05-18 20:22:47 UTC 
That's... curious.  The X log is only reporting VGA, period.  Normally you'd expect to see your other outputs listed as disconnected.

Can you attach dmesg from booting with 'drm.debug=0x04' please?

dmesg from booting with drm.debug=0x04

Hi Adam,

as requested, the dmesg from booting with drm.debug=0x04.

Cheers,

Matthias
Comment 13 Adam Jackson 2010-06-07 18:31:04 UTC 
This should be resolved by Intel DRM driver updates since the beta was released.  Please retest with kernel-2.6.32-33.el6 or later.
Comment 14 Matthias Schroder 2010-06-08 08:31:43 UTC 
I will be glad to test this, but where do I find the newer kernel and drivers?
Comment 15 Adam Jackson 2010-06-16 19:57:15 UTC 
Beta 2 will be publicly available on FTP and RHN.
Comment 16 RHEL Program Management 2010-07-15 14:59:14 UTC 
This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
Comment 17 Matthias Schroder 2010-07-16 11:58:32 UTC 
I am a bit puzzled by Comment 16, I have installed beta 2 now, and the problem with the second video out is solved. So what does comment 16 mean?
Comment 18 Adam Jackson 2010-07-26 15:18:53 UTC 
Comment 16 was added by a bot.  It means "we won't go out of our way to fix this in 6.0".  But since it appears to be already fixed, we don't have to.

Thanks for testing!
