U3223QE, MacBook Pro, Linux PC, sharing mouse and keyboard, fixed!

Dell U3223QE

Dell U3223QE


I have 2 computers connected to a Dell U3223QE monitor:

  1. MacBook Pro 16 2019 running ventura. It connects to the monitor to port 5 - USB-C port see the bottom view here : .
  2. PC running Pop!Os 22.04LTS (based on Ubuntu). I connects to the monitor to port 4 - Display Port
  3. I have a mac keyboard and a mouse that are both wired and they are plugged into the usb ports 9 & 10.

I also have a wired keyboard and wireless mouse for the PC. They are plugged into the PC.

I can switch between the 2 using the joystick behind the monitor but the mac keyboard doesn't work for the PC, it sends my input to the mac.

I installed the Display Manager for the mac and I tried to use KVM but it still doesn't work.

I want to be able to share the same keyboard & mouse for both.

Any ideas on how to get it working?

ok, I got it working by using the 3rd cable, USB-C 1.0 M cable (A to C), connecting the PC and port 8.
