barrier VS tinypilot

For software KVM you can use https://github.com/debauchee/barrier

I use it between a Windows PC & a Macbookpro (Linux version available but I don't have Linux)

Barrier is a Cross-Plattform, open source Synergy fork that works quite well without any additional HW too [0]

Prior to Synergy going to closed source, it was forked into Barrier[0], which then was forked into input-leap[1]. Both open source.

Synergy is open core, these portions are licensed as GPL: https://github.com/symless/synergy-core/#License-1-ov-file

There is an open source fork that branches off version 1.9: https://github.com/debauchee/barrier#what-is-it

libei looks useful. But IDK why libei is necessary to run Barrier with Wayland?

For client systems, couldn't there just be a virtual /dev/inputXYZ that Barrier forwards events through

And for host systems, it looks like xev only logs input events when the window is focused.

Is xeyes still broken on Wayland, and how to fix it so that it would work with Barrier?

With Barrier, when the mouse cursor reaches a screen boundary, the keyboard and mouse input are then passed to a different X session on another box until the cursor again crosses a screen boundary rule.

Barrier is a fork of Synergy's open core: https://github.com/debauchee/barrier

libei:

Barrier appears to handle PC switching only for the keyboard and mouse.

I make one that I put a lot of effort into documenting:

https://github.com/tiny-pilot/tinypilot

It's pretty easy to extend since it's just Python and vanilla HTML/JS/CSS, so there's not much of a toolchain to install.

You can buy it pre-made for $399 or make a DIY one for under $100.

Took me awhile to remember what it was called, but TinyPilot [^0] by mtlynch is pretty cool. Michael sometimes writes about running a hardware business on his blog [^1].

https://tinypilotkvm.com is a great option for this.

You could use the PI to run TinyPilot for IP KVM for one of the PCs: https://github.com/tiny-pilot/tinypilot

TinyPilot Voyager 2 KVM

You can still do TinyPilot yourself without buying their custom product it is much cheaper just use https://github.com/tiny-pilot/tinypilot
