NAME
       systemd-xdg-autostart-generator - User unit generator for XDG autostart
       files

SYNOPSIS
       /usr/lib/systemd/user-generators/systemd-xdg-autostart-generator

DESCRIPTION
       systemd-xdg-autostart-generator is a generator that creates .service
       units for XDG autostart[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.
