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 Michel Dänzer 2020-01-27 17:15:39 UTC 
Description of problem:

Xorg crashes on startup if rotation is configured in xorg.conf for any connected RandR outputs.


Version-Release number of selected component (if applicable):

1.20.6-2.el8


How reproducible:

Always (with an affected configuration, which is rare).


Steps to Reproduce:
1. Configure rotation in xorg.conf Section "Monitor" for any connected RandR output.
2. Start Xorg.


Additional info:

This is a regression in xorg-x11-server-1.20.6-2.el8, caused by one of my fixes for bug 1738670. Upstream fix pending review at https://gitlab.freedesktop.org/xorg/xserver/merge_requests/384 .
Comment 1 Michel Dänzer 2020-01-27 17:37:29 UTC 
Example xorg.conf snippet to reproduce below. The identifier needs to be adapted to match one of the RandR outputs which are connected at Xorg startup (grep the log file for " connected"). Option values "left" or "right" reproduce as well, but not "normal".

Section "Monitor"
    Identifier "DVI-D-3"
    Option "Rotate" "inverted"
EndSection
