Bug ID: 458892
Summary: Crash when the monitors go to sleep
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: platform-drm
Assignee: kwin-bugs-n...@kde.org
Reporter: aleix...@kde.org
Target Milestone: ---
It happens both when 2 montiors go to sleep, also 1. They're on Display Port,
which I find gives more information about the display state than HDMI.
