When I plug my external monitor in, the mirroring option is greyed out.
This worked fine in F21.
I DO have a challenge in that my Belkin KVM is only seems to be allowing 1024x768, eventhough the manual says it supports higher resolution. But this worked fine in F21. And even if I force the laptop panel to 1024x768, mirroring is still not available.
Where might I find a control to fix this?
