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.

Fixed In Version:
Doc Type: Known Issue
Doc Text:
Screen occasionally turns off when "xrandr" is executed With the "Nouveau" driver, RANDR operations combined with heavy 3D load, such as querying the screen resolution, may cause screen flickering. Flickering can be avoided by minimizing concurrent 3D and RANDR operations. Hence, query or resize the screen while 3D usage is minimal.

Description Oliver Ilian 2018-02-15 09:35:36 UTC 
Description of problem:
On a W541 (with Nvidia graphic card) the screen turns occasionally off during execution of xrandr -q. This happens for example when gnome-control-center is started.

Version-Release number of selected component (if applicable):
kernel-3.10.0-693.17.1.el7.x86_64
xorg-x11-server-Xorg-1.19.3-11.el7_4.1.x86_64
Model: W541
Graphic: Nvidia Quadro K1100M

How reproducible:
often

Steps to Reproduce:
1. log in to gnome as user
2. make sure the nouveau driver is not loaded
2. start 50 x glxgear (to get some load on the system)
3. in a second terminal repeat several times: xrandr -q

Actual results:
System flickers occasionally (screen turns completely off for 1 second)

Expected results:
System does not flicker

Additional info:
We have blacklisted the nouveau driver on this model due to https://bugzilla.redhat.com/show_bug.cgi?id=1545546

Comment 3 Oliver Ilian 2018-02-15 14:07:25 UTC 
to add: The NVidia card is not used in this scenario, as the nouveau driver is not loaded. The Intel graphic card is: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
Comment 5 Adam Jackson 2018-08-09 16:13:00 UTC 
Do we still see this with 7.6?
