Bug ID: 389514
Summary: internal screen frequently turns black
Product: KScreen
Version: 1.0.5
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: libkscreen
Assignee: se...@kde.org
Reporter: m.w...@web.de
Target Milestone: ---
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.
