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 7 Ryan Kraus 2016-05-16 12:19:07 UTC 
This ticket is about indirect rending being disabled by default on Xorg 1.17. It can be enabled, in 1.17, by starting Xorg with the +iglx flag. An easy way to reproduce the issue is to run "glxinfo -i".
Comment 11 Rik Theys 2016-05-23 11:32:48 UTC 
Hi,

How can the +iglx option be added to the X server arguments when using gdm? I've tried various settings for /etc/gdm/custom.conf that should do this but none seem to work. It seems setting the X server command in custom.conf is no longer possible.

Are there any plans to revert the default settings to the 1.16 version?

Regards,

Rik

Indeed, you can't, gdm does not have that ability. The best you can do in the interim is replace the Xorg binary with a shell script that execs the real thing with +iglx prepended to the comand line.

Yes.
Comment 15 Karsten Weiss 2016-05-30 14:51:20 UTC 
May I suggest that this issue should be mentioned in the Technical Notes or the Release Notes as well? AFAICS both documents currently contain almost no information about the xorg-x11-server changes although there was a version jump from 1.15.0 to 1.17.4.

Do you have an example of how this could look? I've tried but can't make it work.

No need, i managed to make it work:

Don't know what I managed to screw up before though.
