My groot-ansible will have installed all the required packages and the basic configuration, but I still seem to be missing some steps:

• Under System Settings→Regional Settings→Language add Korean (will install a few debs)
• If groot-ansible did not install ~/.config/autostart/fcitx.desktop log into gnome and run Startup Applications, add fcitx
  • NB: Kubuntu's System Settings→Startup & Shutdown→Add button is broken
• Log out / log in
• Under System Settings→Regional Settings→Input Method
  • Uncheck Only Show Current Language 
  • Shift Hangul across to the right
  • Under Global Config → Trigger Input Method, reset the shortcut if necessary (groot-ansible installs right alt as default, but you probably want the 'Hangul' key)
  • Set skin to dark

If there are still issues, try running from the command line: fcitx-diagnose

Synergy (Not Tested Yet)

No deb release for focal, but you can compile the sources with tag v1.11.1-stable (bionic's synergy 1.08 won't work, qt4→qt5 transition). However, a 1.08 server (bionic) is compatible with a 1.11 client.
