  • Hmmm.. I added some clarification. I don't want to send messages over SSH, I think. I think of notify-send as a terminal app that I can run interactively to the host (not client) PC. I think I understand - notify-send is a client per se on the host machine in its own way - is what you're saying. Does that somehow mean this is not possible to do while in an SSH session? Mind you, I am not trying to get this to appear on the SSH client, only the SSH host/server. Commented Jul 28, 2014 at 17:50
  • @aikeru - notify-send can send messages to the listening notifier daemon. When you login via SSH this environment does not have the info necessary to communicate w/ this notifier, is the underlying issue. Commented Jul 28, 2014 at 18:02
  • So is there any way to attach to the current environment or something like that, such that it has the info needed? Commented Jul 28, 2014 at 18:15
  • @aikeru - much of what I've found shows that setting $DISPLAY=:0 would work, but this does not work for me as well. I'm on Fedora 20 using Cinnamon as my desktop. Using strace to debug this shows that there is a connection that doesn't get done when going through SSH, still investigating what is blocking this. Commented Jul 28, 2014 at 18:50
  • @aikeru - see updates. Commented Jul 29, 2014 at 11:37
