[kwin] [Bug 402827] kwin_wayland segfault on monitor wakeup
https://bugs.kde.org/show_bug.cgi?id=402827 --- Comment #26 from Rainer Finke --- Since Plasma 5.19 beta I can turn off and on the monitor with the power button without any crash of kwin. Seems like there is a fix that helped at least on my system.

Committed on 08/01/2020 at 09:12. Pushed by romangilg into branch 'master'. [platforms/drm] Allow running without outputs Summary: Set outputs enablement also when none outputs are present. This patch is similar to earlier attempt at D17985. Related: bug 389551, bug 398680, bug 413758 Test Plan: Starting without outputs, manual disconnects and DPMS changes. There is still an issue when an output gets disconnected while the DPMS is off. But it's an improvement already.

https://bugs.kde.org/show_bug.cgi?id=402827 --- Comment #17 from Rainer Finke --- After the upgrade to Plasma 5.15 beta kwin doesn't segfault anymore, if the monitor is turned off via the power settings after e.g. 5 minutes. I can then just continue to work with the Plasma session on wayland after pressing a key on the keyboard. But it still doesn't work (with the external AMD GPU), if I turn off and on the monitor with the power button, then there is still a segfault of kwin. -- You are receiving this mail because: You are watching all bug changes.
