Description Joseph Kachuck 2011-01-03 15:56:00 UTC 
Current RHEL and Fedora distributions ship with Nouveau as the default driver for NVIDIA GPUs. This is fine, but Nouveau's KMS presents challenges to users who choose to use the NVIDIA driver instead.

Newer versions of the NVIDIA X driver installer will attempt to disable Nouveau automatically at install time, but the actions that the installer takes have no effect if Nouveau is present in the initrd, as it is on RHEL and Fedora systems. In the past we have asked if Red Hat would be willing to provide a hook script that the NVIDIA installer would run, either to build a new initrd image which includes the configuration directives added by the NVIDIA installer to disable Nouveau, or to add parameters to the bootloader configuration to suppress Nouveau in the initrd.

We would like either to revisit the proposed distribution hook scripts, or to discuss what the best next steps would be to help customers who choose to use Red Hat operating systems and the NVIDIA driver together have a smooth experience. Presently, we have a section in the driver README that discusses Nouveau; please see section 8.1 "Interaction with the Nouveau driver" in chapter 8, "Common Problems" of the README:

Comment 14 RHEL Program Management 2012-07-10 07:48:33 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 15 RHEL Program Management 2012-07-11 02:08:12 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
