This report is created in order to summarize related report caused by the same
issues of systemd-xdg-autostart-generator in 15.5.

systemd-xdg-autostart-generator is a mechanism to start XDG autostart (e.g.,
/etc/xdg/autostart) instead of desktop environments. In Leap 15.5, KDE plasma
started to use this mechanism.

However, due to the following problems, xdg-autostart-generator cannot start
desktop files derived from Leap 15.4. Some essential services including IBus
does not work in 15.5 (#1211977). 

* systemd-xdg-autostart-generator inappropriately ignores desktop files with
X-GNOME-Autostart-Phase (#1201728) [1]
* systemd-xdg-autostart-generator cannot start process that forks another
process [2, 3, 4]
