Fedora 23 Cannot Recognise Auxiliary Monitor on a Dual Head System
Last modified: 2016-12-20 09:41:54 EST
Description of problem: Fedora 23 cannot find the second monitor. I have tried both GNOME and KDE but the monitor does not become active in either case. The monitor is active in initial boot (I see boot progress on it) but as soon as the GDM kicks in, it goes blank. I have experimented with the various monitor settings under both KDE and GNOME and nothing I do will activate it, making me assume it is an X Server issue. (I have not experimented with Wayland yet.) I am running a dual head system (IBM Thinkpad T540p) with a Lenovo ThinkVision monitor. How reproducible: Every time. Steps to Reproduce: 1. Boot Fedora 23 Beta. Actual results: GDM (and subsequently GNOME and KDE) cannot activate my auxiliary monitor which was detected and working correctly under F22. Expected results: Dual head monitor should be detected. Additional info: I can supply log data and sys config info on request. Just tell me what you need and I will be happy to help. Thanks.
Update: Wayland cannot detect the second monitor either.
My bug is possibly related to this one: https://bugzilla.redhat.com/show_bug.cgi?id=1256712 As per comment 2 on that bug, dropping back to kernel-4.1.4-200.fc22.x86_64 allows me to use the second monitor on GNOME/Wayland but not on KDE.
This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '23'. 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 23 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 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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.
