            Bug ID: 329958
           Summary: KDE Goes to black screen with mouse pointer after
                    plugging in HDMI monitor and powering up from sleep
    Classification: Unclassified
           Product: kdelibs
           Version: 4.11.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: kded
          Assignee: unassigned-bugs at kde.org
          Reporter: stevenpuzzle at gmail.com

Application: kded4 (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed: Powered up from sleep with
HDMI monitor plugged into laptop that was not plugged in before sleep. 

- Unusual behavior I noticed: Screen was not "frozen", just black with working
mouse pointer that worked on both laptop and external monitor. No keyboard or
click action seemed to correct. Unplugging and replugging HDMI fixed.

- Custom settings of the application:

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
