Bug 1211977

This bus is same as boo#1202841
https://bugzilla.opensuse.org/show_bug.cgi?id=1202841


Recent changes to 15.5 (after beta phase?) switch to use sytemd-autostart-generator to launch /etc/xdg/autostart/*.desktop on KDE Plasma session instead of KDE itself [1].

It is known that systemd-autostart-generator cannot handle desktop entries that have a command starting a daemonized process and exiting soon (in this case, ibus-daemon -d) [2].

To fix this, I will backport a newer version of ibus-autostart script to Leap 15.5.

A fix in Tumbleweed is not applied to Leap 15.5 because ibus version is older than expected. So I took another approach; I modify ibus-autostart so that it starts ibus-daemon without `-d` if the current desktop is KDE.

The updated package is available here:
https://build.opensuse.org/package/show/home:ftake:branches:openSUSE:Leap:15.5:Update/ibus

This package is from SLE 15 SP4. I need help of SLE maintainer.


Until the updated package is released, you can avoid this problem by modifying ibus-autostart as the following:

```
#!/bin/sh

test x"$INPUT_METHOD" = x"ibus" || exit 0

# GNOME starts ibus by itself
case "$WINDOWMANAGER" in
    *gnome*)
        exit 0;;
esac

# sleep for a little while to avoid duplicate startup
# sleep 2

# boo#1211977: xdg-autostart-generator cannot launch ibus with -d
if [ "$XDG_CURRENT_DESKTOP" = "KDE" ]; then
    exec ibus-daemon --xim
fi

ibus-daemon --xim -d
exit 0
```

I have submitted a maintenance request:
https://build.opensuse.org/request/show/1090703

I've revised the updated package and remove X-GNOME from ibus-autostart.desktop

https://build.opensuse.org/request/show/1090952

Also considering fix in systemd side.
Although some issues have been already resolved, but it still has problem:

Re-posting here my question from build.suse.de:

Are all the changes to ibus-autostart.desktop (removal of all X-GNOME-* entries) really necessary?

According to systemd-xdg-autostart-generator's man page, no service will be generated if X-GNOME-Autostart-Phase is set to any value, so that one should be removed indeed. But the other keys (X-GNOME-AutoRestart and X-GNOME-Autostart-Notify) don't seem to be considered, so they could stay?

Yes, they should be able to stay.
I removed them all (in Tumbleweed) because ibus-autostart does nothing under GNOME.

Since some other packages need to be fixed, fixing KDE or systemd side will be a better approach.

Does this mean that https://build.suse.de/request/show/302830 should be rejected, or is it still needed until KDE and/or systemd are patched?

I hope this fix will be unnecessary soon (but neither of KDE and systemd maintainer would not accept the fixes for now).

SUSE-OU-2023:3550-1: An update that has one fix can now be installed.

I confirmed ibus updated and start automatic when KDE plasma start.
