I filed a bugzilla report. It's https://bugzilla.redhat.com/show_bug.cgi?id=1397864 Meanwhile I did some more poking around and found something that appears very interesting. To quote a comment I added to the above bugzilla report: ================================================== Apparently, kernels newer than 4.8.4 think my system has 2 monitors attached to it. It only has one. It has never had two. I'm using the embedded graphics for my one and only monitor. I have never added a second video card. When I run the KDE system settings app and use the display applet, it sees my main monitor and second monitor it describes as a laptop monitor. This system is not a laptop. It is a desk-side system. Only kernels newer than 4.8.4 (ie, 4.8.8.and 4.8.10) show this. The 4.8.4 kernel correctly determines I only have one monitor. ================================================== I've got a workaround for now. I can run system setting and choose the display and monitor applet. That's where I see two displays. After some back and forth I've found that clicking "Unify Outputs" gives me one display. Icons are all messed up but I can live with that for now. Charlie On 11/22/2016 05:27 PM, Charles R. Dennett wrote: > Thanks for the suggestion.
