I've been doing something insane that keeps Barrier working. I have Firefox and KeePassXC flatpaks installed and forced to use X11 fallback so they can autotype together. And coincidentally, that means Barrier can mouse off the server screen to the client machine if I have Firefox maximized on that edge. And never any other time. But maybe that's helpful to someone.

This post reminded me how stupid that was. So I installed input-leap on a distrobox arch container. Now it all instantly works. My existing Barrier clients just connected as usual with no tweaks. Apparently it was already installed in Aurora-dx directly, but that version didn't work for some reason. I suppose I'm glad I went the long way and you reminded me to try.

During a rare internet-but-not-power outage, my roku tv refused to turn on or give me any option to switch inputs because it couldn't update.
