systemd-xdg-autostart-generator is a generator that creates .service units for m[blue]XDG autostartm[][1] files. This permits desktop environments to delegate startup of these applications to systemd(1) .
Units created by systemd-xdg-autostart-generator can be started by the desktop environment using "xdg-desktop-autostart.target". See systemd.special(7) for more details.
XDG autostart may be conditionalized using both standardized and non-standardized keys. In order to handle these, the generator may create one or more ExecCondition= entries. For non-standardized keys, well-known helper binaries provided by Desktop Environments are used. All external helpers must detect their corresponding desktop environment and must return success when run in a different environment. This is important as all ExecCondition= directives must succeed for an application to be started.
