Does Synergy work with multi monitor setups? I've enjoyed Barrier but it doesn't work when any of the machines have multiple displays so I've ditched it for now.
Nowadays you have to look at the logs and search through a pile of github issues to find the right solution to make it work, but once it's up it's pretty trouble free.
Only real pain point is clipboard sharing, which works for small clipboards, but, copy too much text and it takes forever to switch.
