Desktop file format

Confused about all the .desktop files in Gnome / KDE? There is an official spec at: www.freedesktop.org/wiki/Specifications/desktop-entry-spec.

Where are they?

All User files are in /usr/share/applications
Personal files are in $HOME/.local/share/applications

Gnome additions: / Autostart

 
X-GNOME-Autostart-enabled=true

should be set for files in $HOME/.config/autostart. This describes autostart applications. More info on autostart: KDE Bug #170817.
