Created attachment 1153610 [details] journalctl.log Description of problem: Laptop has built-in display and a 24" external display connected via mini-displayport. Gnome-shell settings Displays panel reports two instances of "Built-in display" and there really is a phantom 3rd display that I can move the mouse arrow to and totally lose track of it (it appears on no display). Version-Release number of selected component (if applicable): kernel-4.5.2-302.fc24.x86_64 xorg-x11-server-Xorg-1.18.3-1.fc24.x86_64 xorg-x11-drv-ati-7.6.1-3.20160215gitd41fccc.fc24.x86_64 gtk3-3.20.3-1.fc24.x86_64 mesa-dri-drivers-11.2.0-1.20160414.fc24.x86_64 clutter-1.26.0-1.fc24.x86_64 mutter-3.20.1-1.fc24.x86_64 How reproducible: Always Steps to Reproduce: 1. Create USB stick using dd, with Fedora-Workstation-Live-x86_64-24_Beta-1.4.iso 2. Default boot and liveuser login environment, no changes, this appears to be only an Xorg session, no wayland is found in journalctl. 3. Actual results: See screen shot. Display 2 is the real built-in, display 3 is the external, and display 1 is phantom (does not exist, that's where the mouse arrow vanishes if I move the mouse completely to the far right, as soon as it goes off the #3 24" display, it vanishes. And I can, in the blind, move it back to the left and it reappears on display #3. So it acts like there is a real display 1 but it's confused. Expected results: there should only be one built-in display as Primary, and the Secondary is the 24" external. Additional info: Identical setup works fine by default in Fedora 23 with the same kernel version.
If I click on either built-in display (either display 1 or 2) and choose the "Turn Off Don't use this display" option, the built-in display is turned off.
Created attachment 1153638 [details] journalctl2.log If I use boot param i915.nomodeset=0 the problem doesn't happen. So it's like it sees two built-ins just because there's both radeon and intel graphics on this system.
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '24'. 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 24 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 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 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. Thank you for reporting this bug and we are sorry it could not be fixed.
