I have a X220 with an external monitor connected to it via docking station. I have configured KScreen so that one screen extends the desktop. I am running KDE Neon Git stable. Since a few weeks the following phenomenon appears frequently with no discernible pattern. Both screens turn black for a short moment. The external screen then shows what it has shown before. The internal screen remains black. The internal screen seems to still exist, because there is no reconfiguration. It appears that the panel and the other windows remain on the black screen. The shown configuration in KScreen remains unchanged. The problem is easy to fix temporarily by changing the KScreen config to something else for the moment and the reapplying the old one. Installed version of Kscreen + libkf5screen7: 4:5.11.5+p16.04+git20180125.0934-0 I have tested if this might be a hardware problem by running Windows for a few hours. There this did not happen. I guess you need some more detailed info on my configs? Please let me know what commands I need to run.
Can you attach the following information to this bug-report, please? It'll help me to figure out what the problem may be. https://community.kde.org/Solid/Projects/ScreenManagement#Debugging_Information It would be very helpful if you could mark in kscreen.log where the blacking out occured, so I can clearly see what events triggered it. Thanks!
I am trying to provide the information, but I have problems doing that. I have followed the information provided in the link and created the script, made it executable and started it. But does not leave any new information in ~/.local/share/kscreen/kscreen.log The file existsed before, but the oldest information is 3 weeks ago.
