/usr/src/debug/plasma-workspace-5.5.4/shell/main.cpp:181 I created new user and met the same problem => it is not a configuration issue. Version-Release number of selected component (if applicable): plasma-workspace-5.5.4-2.fc23 How reproducible: always Steps to Reproduce: 1. simply start plasmashell. May it be when starting KDE or from konsole.. 2. 3. Actual results: plasmashell hangs Expected results: Additional info:
After reboot, plasmashell starts correctly. This I suspect this xorg-x11-drv-intel update to be the root cause of this problem: https://bodhi.fedoraproject.org/updates/FEDORA-2016-606ca05253 I downgraded it before.
Perheaps re-assign this bug to xorg-x11-drv-intel? Or will plasmadesktop be fixed so it won't break with DRI3 enabled?
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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
