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 Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Since this happened, I trashed my partition and had to do a fresh install of Kubuntu 13.10. I can not reproduce now. I suspect, as with many things like the KWallet pop-up after log in, the fresh install cleaned up issues remaining from upgrading. I started in the 11's somewhere.
specifications: Lenovo t440s with docking station, external monitor connected to docking station with DVI cable. Fedora 21 with KDE plasma-workstation This bug annoys me every time a turn-on my computer without docking station and external monitor. Then turn-off(not sleep or hibernate) plug in to docking station with attached ext. monitor and after that turn-on -> black screen (probably plasma-desktop not loaded correctly) Any other applications, shortcuts works fine. Nothing special in logs nor in processes observed. Seems like desktop wallpaper and all widget are covered with black color, because when trying to unplug monitor or detach from docking station, the desktop shows for half a second or less. Reproducible: 100% Steps to reproduce: 1. power-on notebook without any connected HW(mouse, monitor, etc) 2. normal power-off 3. attach to docking station with external monitor connected 4. power-on -> log-in 5. black desktop screen appears Actual results: plasma-desktop is all black and inactive Expected results: plasma-desktop should load and work after log-in Possible workaround: 1) When I reinstall KDE plasma desktop group using yum, it works as expected for 1-2 times, then happened again. 2) Start the notebook alone(without plugging it into docking station), log-in -> attach to docking-station(monitor will not be detected automatically) -> system settings -> display and monitor -> manually enable external monitor - works for me Contact me pleae on email if you will need some log files or something.
This bug is reported on libsolid which is the kdelibs4 version of the solid library. It is now in maintenance mode. If you think it should still be fixed in the KDE Frameworks 5 version of solid please move it to or report a bug on frameworks-solid or Powerdevil.
I see the same issue with a three monitor setup. Many times the third monitor (same each time) will start black with no interactions. I can place windows on that screen, but no background or interaction. The only solution I've found is to enable and disable the monitor. Which results in a crash similar to #351777. qt 5.5.0 plasma-framework 5.14.0 plasma5-workspace 5.4.1
I am also experiencing this bug. I upgraded my system yesterday (11/16/15) and KDE Plasma had a huge upgrade that came down the pipeline. Since then, every time I plug my HDMI cable into my laptop (Macbook Pro Early 2015), my laptop screen goes black and the external monitor does, too. I can see a pointer on the screen but no desktop. I cannot click anything and am forced to do a hard reboot. Previously, the HDMI external monitor connection had been buggy, but only when returning from sleep mode and was 90% of the time functioning. Now it is functioning 0% of the time. Arch Linux 4.2.5 KDE Plasma 5.4.3
Same here, my HTPC connects to a HDMI TV, when I turn off/on the TV, plasma desktop will be gone, leaving only a mouse pointer. Arch Linux 4.2.5 KDE Plasma 5.4.3
the same bug occurs on my setup kubuntu 16.04 plasmashell 5.5.5 dual (or triple) screen setup everytime one of the screens goes to sleep or is powered down plasma shell "kinda" crashes.. (not ontirely - otherwise it would just restart) sometimes on one of the screens the wallpaper is still visible and rightclick opens the context menu.. usually the screens are just black and input events are not recognized anymore.. the rest of the system (kwin, other programs) continue to work properly.. so starting krunner and killing && restarting plasmashell gives you a working system again. it seems to be irrellevant if the display is connected via usb (displaylink), hdmi, dvi or displaylink.
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Please try again with the latest version and submit a new bug to frameworks-solid if your issue persists. Thank you!
