So I've modified /etc/xdg/autostart/ibus.desktop like this: kumiko:~ # diff -burNE /root/ibus-autostart.desktop /etc/xdg/autostart/ibus-autostart.desktop --- /root/ibus-autostart.desktop 2022-07-19 17:06:19.120630687 +0200 +++ /etc/xdg/autostart/ibus-autostart.desktop 2022-07-20 21:09:19.522177492 +0200 @@ -8,8 +8,9 @@ Type=Application StartupNotify=false NoDisplay=true -X-GNOME-Autostart-Phase=Applications X-GNOME-AutoRestart=false X-GNOME-Autostart-Notify=false -X-KDE-autostart-after=panel +X-KDE-autostart-after=org.kde.plasmashell X-KDE-StartupNotify=false +X-KDE-autostart-phase=1 + and it still doesn't start. lemmy@kumiko:~> systemctl --user status app-ibus\\x2dautostart@autostart.service ��� app-ibus\x2dautostart@autostart.service - IBus Loaded: loaded (/etc/xdg/autostart/ibus-autostart.desktop; generated) Active: failed (Result: timeout) since Wed 2022-07-20 21:11:35 CEST; 2min 13s ago Docs: man:systemd-xdg-autostart-generator(8) Main PID: 2716 (code=exited, status=0/SUCCESS) CPU: 1.648s Jul 20 21:11:29 kumiko systemd[2317]: Starting IBus...
