Created attachment 815736 [details] Screencast demonstrating the external display disconnection problem. Description of problem: I'm participating in the Fedora 20 Graphics test week. When following the http://fedoraproject.org/wiki/QA:Testcase_radeon_multihead test case, I encountered the problem that the X server/driver doesn't detect external display disconnection properly. Version-Release number of selected component (if applicable): kernel-3.11.6-300.fc20.x86_64 xorg-x11-server-Xorg-1.14.3-4.fc20.x86_64 xorg-x11-drv-ati-7.1.0-6.20130408git6e74aacc5.fc20.x86_64 gnome-shell-3.10.1-1.fc20.x86_64 control-center-3.10.1-1.fc20.x86_64 How reproducible: Always. Steps to Reproduce: 1. Connect the external display 2. The system automatically detects the display and extends the GNOME desktop to it. 3. Disconnect the external display Actual results: Nothing happens. Expected results: The system should detect the disconnection and adjust the display settings accordingly. Additional info: I recorded a screencast showing the problem. When I ran xrandr (after the external display was disconnected), things are updated. But at the same time GNOME's screencast suddenly ended.
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 EOL if it remains open with a Fedora 'version' of '20'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 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, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. 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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
