Description of problem: Putting Option "NoDRI" in the Device section of the Radeon card in xorg.conf does not work. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.6.3-3.13.el5 How reproducible: always Steps to Reproduce: 1. Put Option "NoDRI" in the Device section of the Radeon card in xorg.conf 2. Launch X (init 5) 3. # cat /var/log/Xorg.0.log | grep NoDRI (WW) RADEON(0): Option "NoDRI" is not used Actual results: DRI is not disabled. Expected results: DRI disabled. Additional info: I think it was reported to Fedora-devel : http://www.redhat.com/archives/fedora-devel-list/2006-September/msg00593.html
If DRI could be disabled, this would help diagnose a bit more bug 465144 : https://bugzilla.redhat.com/show_bug.cgi?id=465144
from radeon(4): Option "DRI" "boolean" Enable DRI support. This option allows you to enable to disable the DRI. The default is off for RN50/ES1000 and on for others. This is clearly misconfiguration IMHO. Closing as NOTABUG.
Actually, this is from Rawhide. Manpage on RHEL5 doesn't mention any DRI option at all. Does (by chance) Option "DRI" "boolean" work for you? If yes, we should fix documentation.

MODIFIED xorg-x11-drv-ati-6.6.3-3.24.el5 built in brew.
Tested, confirmed to work: "NoDRI", "DRI" "false", and nothing, on assorted hardware (with and without actual DRI support), checking each of Xorg logs, glxinfo output, and glxgears performance.
