Bug ID: 359650 Summary: plasmashell crashed after screen detached Product: plasmashell Version: 5.5.4 Platform: Fedora RPMs OS: Linux Status: UNCONFIRMED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: ber...@codewiz.org CC: bhus...@gmail.com, plasma-b...@kde.org Application: plasmashell (5.5.4) Qt Version: 5.5.1 Operating System: Linux 4.3.5-300.fc23.x86_64 x86_64 Distribution: "Fedora release 23 (Twenty Three)" -- Information about the crash: I detached my laptop from the external monitor, and both plasmashell and kwin crashed almost simultaneously. I couldn't capture the kwin crash. Additionally, KDE does not seem to detect monitor plug/unplug events automatically. At least, not reliably. Everything works fine in Gnome. This system is using the intel driver: xorg-x11-drv-intel-2.99.917-19.20151206.fc23.x86_64. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library
