Bug ID: 375280 Summary: Screen is black unless external monitor is plugged in Product: plasmashell Version: 5.5.5 Platform: Ubuntu Packages OS: Linux Status: UNCONFIRMED Keywords: drkonqi Severity: crash Priority: NOR Component: general Assignee: k...@davidedmundson.co.uk Reporter: nevan.wich...@gmail.com CC: bhus...@gmail.com, plasma-b...@kde.org Target Milestone: 1.0 Application: plasmashell (5.5.5) Qt Version: 5.5.1 Operating System: Linux 4.4.0-45-generic x86_64 Distribution: Ubuntu 16.04.1 LTS -- Information about the crash: My laptop screen is always black unless my external monitor is plugged in. If I restart the computer without the monitor plugged in, it works fine untill I login, and then the laptop screen goes black. The screen works again as soon as I plug the monitor in. It doesn't matter if the monitor is turned on or not. The laptop was working fine untill I started using it with an external monitor then I started having this problem. About half of the time when I plug the monitor back in again I see this crash.
