Description Robin Green 2011-02-17 13:31:32 UTC
Description of problem:
I tried to disable DRI as described at http://fedoraproject.org/wiki/How_to_debug_Xorg_problems to debug a display corruption problem, but Xorg read the option and still enabled DRI anyway. Contrary to what the radeon man page says.

Version-Release number of selected component (if applicable):
xorg-x11-drv-ati-6.14.0-2.20110204gita27b5dbd9.fc15.x86_64

How reproducible:
Haven't tried

Steps to Reproduce:
1. Add line         Option "DRI" "off"
to Xorg.conf
2. Logout
3. Login
4. Examine /var/log/Xorg.0.log
  
Actual results:
"Direct rendering enabled", no indication that DRI has been disabled, apart from the fact that the Option line that I added is echoed.

Expected results:
Direct rendering should be disabled - or the man page should be updated to reflect the fact that this option no longer works.

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

Please add drm.debug=0x04 to the kernel command line, restart computer, and attach

* your X server config file (/etc/X11/xorg.conf, if available),
* X server log file (/var/log/Xorg.*.log),
* output of glxinfo |grep rendering,
* output of the dmesg command, and
* system log (/var/log/messages)

to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.

Comment 2 Fedora End Of Life 2012-08-07 19:12:33 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
