How to make liferea start hidden in the system tray?
Use :
liferea –mainwindow-state=hidden
I’ve added this command in the Startup Applications tab in System->Preferences->Sessions (or Dekstop->Preferences->Sessions if you’re using an older Gnome) so it automatically starts up hidden when I log-in.
You can see other options liferea accepts with:
liferea –help
as is common with all gnu/linux applications.
