http://bugzilla.opensuse.org/show_bug.cgi?id=1110421 Bug ID: 1110421 Summary: Brightness change without effect after suspend (and removing external screen) Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: cyberbeat@gmx.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- To reproduce (hwinfo see underneath): 1. Start laptop with current kde plasma 2. configure kde (kscreen) to only use external screen (DVI as main output), internal screen LVDS1 off 3. suspend laptop 4. remove external screen by removing laptop from docking station 5. awake laptop from suspend ==> 6. now the internal screen is active, but dimmed to the lowest brightness.
