I have two computers in the same network, both running Kubuntu 22.04.
How to use screen of one computer (say A, an all-in-one/laptop) as an external display for the other one (say B, a desktop)? Is it also possible to play the audio of B through A?
I don't want to mirror screens (which can be done with VNC/Chrome Remote Desktop). I want to use the monitor of the first computer (an all-in-one) as an external display for the second one.
I have tried RealVNC, but it noticeably lags, and does not support audio either.
