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 3 Søren Sandmann Pedersen 2013-09-09 21:51:05 UTC 
I get the error message:

      Number of created screens does not match number of detected
      devices.  Configuration failed.

and then no file is created. However, I get that with a physical Intel chip as well, and it appears to be a general RHEL 6.4 bug.

Gerd, can you be more specific about what happens when you run X -configure?
Comment 4 Gerd Hoffmann 2013-09-10 06:29:04 UTC 
Pheww, it's been a while.  Now I see exactly the same behavior you are seeing.

IIRC it was a different failure mode a few months back, with the versions
in the initial report:  "X -configure" successfully created a config file,
but "X -config $newfile" failed to start with it.
Comment 5 Søren Sandmann Pedersen 2014-06-10 16:05:23 UTC 
Looking at this again, there are at least two problems.

The first problem is that the modesetting driver is chosen in preference to the qxl driver during "-configure" processing. That is wrong since modesetting is a fallback driver that shouldn't be chosen ahead of a hardware specific driver. The fix for this is available upstream:

    http://cgit.freedesktop.org/xorg/xserver/commit/?id=63c48de63becdee680e90cb2363984c2f8f77fd1

The second problem is that when the modesetting driver is being configured, a crash occurs, apparently because the PreInit function pointer is NULL. I don't know any more details than that.

When the first problem is fixed by applying the linked patch, X -configure does produce a working configure file for me with the QXL driver.

So I am moving this bug to the X server component and suggest applying the patch above to RHEL 6.

It may or may not be interesting to fix whatever is going on in the modesetting driver that makes it crash.
