I've used Multiplicity in the far past, and am again at a point where it will be useful (working from home on employer provided laptop as secondary device, my desktop as primary). I can slide the mouse and keyboard over to the other machine just fine. I can drag and drop files from one to the other just fine, too. It's what I re-purchased Multiplicity for in the first place, this morning.
However -- KVM mode sounds great! I'd love to be able to use my mouse and keyboad on the other device, and then with a flick of a few keys, bring that screen over to my desktop.
When I try however, I get a big, gray screen of nothing. If I set it to black background in the settings, I get a big black background. Nothing else. I've tried full screen and windowed. I've tried 1:1 and shrink/stretch. Nothing will get the display to come over. I don't even get a thumbnail of the remote screen in the picker.
I've turned off firewall and antivirus completely in case they were causing issues, but no changes.
RDP works with the remote desktop client, so there's always that, but Multiplicity would be better.
Also -- both computers are connected on 5ghz wireless, private network, same room as the access point, on the same desk. The network sustains Nvidia Shield streaming with no issues.
Desktop: Win10x64 Home, i7x4770, 16g ram, nvidia 980
Laptop: Wind10x64 Pro, i7x6700 16d ram, Intel HD gfx/Nvidia 960m combo.
VM-Ware is installed on the desktop (I mention because an old VNC program wouldn't run with VMWare installed)
Hyper-V is installed on the laptop (Mentioned in case related to issue above. I have not tried to remove either yet, as that's my last steps if I can't get any help).
At a loss!
