Op has a Linux desktop with a usbc hub attached to it. The hub has all their shit plugged in so when they wanna use their laptop they just unplug the hub from the desktop and plug it into the laptop.
Op wants to get rid of the hub and just plug their laptop into their desktop (or into the hub or something) and get access to the desktops resources like keyboard, mouse, monitor and Ethernet.
Did I get that right?
If so, You Can’t Do That.
You actually can, but it’s a huge insane headache! Resource sharing that just works is a plan9 thing, not a windows or Linux thing.
Some possible workarounds:
Put the Ethernet on the hub. Get a usb network adapter with Linux and windows support and use that.
Get a little Ethernet switch and a couple of wires instead and then you have Ethernet when you put the laptop on the desk.
Get a little switch and some wires instead, and use something like barrier (the fork of synergy) for keyboard and mouse sharing.
