Bug ID: 456396
Summary: Crash when turning off and back on a display
Product: kwin
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: platform-drm
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
It happens every time I turn off a display and back on (i.e. with the hardware
button on it). It does trigger a reconnect in DRM code (not a new thing, only
happens when turning it back on which is a bit weird).
