Because that doesn't do the same thing. The point is to have two monitors connected to separate machines, and use the same mouse and keyboard to control both of them.

RDP still still like it would be a better solution, one mouse and keyboard for both PCs and not only that you could have both PCs dual screened.

The point is you don't always want both PCs dual screened. I have my setup prepared for both (using Synergy and a KVM switch): Sometimes I need the screens to show each separate machines desktops, but want to be able to quickly switch keyboard/mouse between them. Sometimes I want one machine to occupy both.

For the latter a hardware KVM switch is vastly superior to RDP. For the former, no RDP server/client I know of provides a solution.

I'm still not sold. RDP does all the configs you've mentioned, dual screen, single screen, being able to see both screens at the same time plus there is the very nice feature of being able to copy paste between computers and peripheral passthrough.

I've not seen an RDP client that provides the capabilities you're describing without e.g. having one of the machines control both screens and putting an RDP client full-screened on one of them, and because of the stutter and CPU overhead I get even with a hardwired network connection that's not a viable option.

I'd be overjoyed if there was a reliable way to do this, but it will need to have each machine controlling it's own screen and pass mouse events between them, similar to how synergy does - having one or both of them rendering desktop of the other is way too laggy, even hard-wired.

I also need a solution where I can disconnected either machine at any time without disrupting anything, which rules out a solution where one machine controls both screens, or where the keyboard and mouse is only physically connected to a single machine.

If there are any RDP clients which can work together to pass mouse events between them the way Synergy or this hardware hack does, I'd be overjoyed (but neither will replace my KVM switch for the occasions I want one machine to control both screens)

> plus there is the very nice feature of being able to copy paste between computers and peripheral passthrough.

Synergy also provides the copy-paste (though I'd actually prefer not to be able to, as I use it between a personal and work machine I don't want to pass more than the bare minimum of data between), and the KVM switch provides the peripheral passthrough.

In many cases remote desktop is a great solution. However, a hardware based KVM can be preferable for several reasons.

Security: remote desktop requires the machines to be on the same network.

Performance and compatibility: hardware accelerated rendering often does not play nice with remote desktop.

I have used Remote Desktop through private VPNs and have been able to connect to my workstation from cities away and performance has been good enough to do video editing and some 3D work.

RDP is really great compared to other solutions like VNC or Xserver. Im really sad there is nothing similar for Linux. Anyone?
