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 of problem:
Unable to create X session with turing GPU, tested with TU104 and TU117, when using /etc/X11/xorg.conf . conf file was automatically generated and driver for GPU is nouveau. When driver for GPU is set to modesetting or there is no xorg.conf X session will be created and gpu is fully functional.
Can be also reproduced on RHEL 8.4
How reproducible: 100%
Steps to Reproduce:
1. have turing GPU
2. create xorg.conf
3. try to log into X session from gdm
Actual results:
you will be returned into GDM
Expected results:
you will get X session

> conf file was automatically generated and driver for GPU is nouveau.
What automatically generated it? We use the generic modesetting X driver by default for Tesla and newer for NVIDIA, which is like GeForce 8000 and six generations older than Turing, so it's not especially surprising that the nouveau X driver wouldn't work.
xong.conf was generated by Xorg -configure. For this pascal gpu ( GP108 [GeForce GT 1030] ) what is predecessor of turing it works just fine with nouveau inside xorg.conf
The nouveau (x.org) driver does not in fact support Turing or newer, you have to use the generic driver named 'modesetting'. We should probably fix X -configure to not configure nouveau at all to be honest.
This is an xserver bug if it's anything, nouveau upstream doesn't support Turing or Ampere and we're not likely to use its support even if it did.
