Synergy and SDDM

For SDDM to connect to a synergy server on archlinux, edit /usr/share/sddm/scripts/Xsetup and add:

/usr/bin/synergyc <server IP or server hostname>

There’s just a little problem if you have more than one monitor. The default Xorg config mirrors all screens. That’s no problem, since KDE sets it all up properly. Unfortunately synergyc doesn’t register the changes, so you have to restart it. Since by then synergyc is running as root, you can’t kill it as user. But fear not, there’s a workaround:

  • Allow the user to execute /usr/bin/killall synergyc as root without password (see https://tollana.d-tor.org/notes-to-self/?p=620)
  • Kill all synergy instances in an autostart script and start a user instance preferably in the systemd user session:
#!/bin/bash 
sudo /usr/bin/killall synergyc 
systemctl --user restart synergyc
  • make it executable, put it somewhere the user can access it and auto-start it. In KDE: System Settings -> Startup and Shutdown -> Autostart -> Script File
  • make sure that you have synergyc.service in $HOME/.config/systemd/user

ExecStart=/usr/bin/synergyc --no-daemon <Server IP or Hostname>

This works with KillUserProcesses=yes in /etc/systemd/logind.conf.
