PC screen real estate...

I now have a Raspberry Pi set up on one of the four monitors in the shack. The original layout was two screens at the top on Linux, then bottom left on Windows and bottom right - central to where I sit on the Mac as the main screen. But that layout had two major issues... I use a program called Barrier to basically act as a KVM switch for the three systems with the Mac as server. That way the Mac mouse and keyboard controls any of the systems, although it can be awkward sometimes where Windows expects keys which Apple doesn't have. But Barrier does not understand dual monitors and so moving the mouse up from the Mac got to the Linux box fine, but moving it down from the left hand screen would not get to Windows as the program does not see it being physically there. I could live with that, except for issue two... The main issue was with the Linux screens being at the top and thus making me sit back or crank my neck upwards, not a good position. So... I got to realising that although I use both screens on the Linux…
