I've been meaning to try out barrier. How do you like it? Is it responsive/fast? I had synergy running across linux/mac machines a number of years ago and it wasn't super reliable back then..
I have been using synergy for 6 or 7 years. Barrier the past year. It works reliably, more so then synergy, and I'm typing this reply through barrier right now :) It also fixes a few quirks I had like xorg screen changes wasn't reflected in synergy and it would start having weird boundaries.
