The configuration file generated for a dual head ATI is incorrect to the extent that the system does not drive the secondary display with generated xorg.conf file but a manually generated xorg.conf file does drive the secondary monitor. Both are attached. This behavior occurs with system-config-display-1.0.37-2 The problem was produced using an ATI Technologies Inc Radeon RV200 LX [Mobility FireGL 7800 M7] chipset on an IBM Thinkpad A31p laptop. However, given the many fedora-list messages (among others) on this topic the problem should occur with most any nvidia or ati based system. To reproduce the problem, start with a default, working single head configuration. Use s-c-d to select the use of dual head. Select spanning desktops for a Desktop layout. After logging out, GDM displays the login screen on the primary monitor and the secondary monitor does not display anything. On the system being tested, the secondary monitor power led blinks green to indicate the absence of signal. Next, log in. The system acts as if dual head is active (indicated by selecting s-c-d from the main menu and noting that one-half of the root password dialog is displayed on the right side of the primary monitor.) Also, the X log file (attached) indicates that the secondary monitor was not detected. It should also be noted that an xorg bug introduced with FC5 broke dual head support on nvidia and ati drivers. This bug is now fixed in Rawhide, FWIW. Also, s-c-d worked fine with FC4 so one might argue that the ati/nvidia drivers might not be doing the right thing in response to a given xorg.conf.

Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
First off, the form does not offer me the ability to change the status. Don't you just hate that? I certainly do. Second, I installed KDE Live Fedora 9 Beta, then did an update as of this morning and retested. With two external monitors attached to my laptop, s-c-d does absolutely nothing when I click on OK in the DUAL-HEAD tab after configuring my Samsung Syncmaster 245 monitor. I'm guessing that there might be logs with results somewhere but this looks like pretty clear wrong behavior. I'll look forward to the next response, which I'm expecting sometime in 2010 when this bug goes through the "maybe the problem went away" cycle one more time. -pmr
One more thing. The device is now a nvidia device, no longer an ATI, but I suspect it should not matter. -pmr
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
