If you use Geary, which last I checked was the only usable e-mail client for mobile GNU/Linux, you may have noticed that, if you close the Geary window, Geary continues running in the background so that it can periodically check for mails and notify you of them. This makes sense, but sometimes you may want to really close it. Then this menu entry will do wonders:
[kevin@plasma-mobile ~]$ cat .local/share/applications/Geary\ Killer.desktop [Desktop Entry] Comment= Exec=geary -q GenericName=Stops background Geary Icon=mail-mark-junk Name=Geary Killer NoDisplay=false Path= StartupNotify=false Terminal=false TerminalOptions= Type=Application X-KDE-SubstituteUID=false X-KDE-Username=
Just use that whenever you want Geary to really go away. It will gracefully quit it with the
geary -q command Geary itself provides.
