            Bug ID: 339270
           Summary: KDE doesn't automatically launch the input method
                    framework(e.g. ibus-daemon)
           Product: kde
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: gemfield at civilnet.cn

I am using the latest kubuntu version:
http://cdimage.ubuntu.com/kubuntu-plasma5/daily-live/20140919/utopic-desktop-amd64.iso

1, when do normally login, KDE doesn't launch the input method framework(e.g.
ibus-daemon), thus input-method doesn't work. The corresponding ps tree is:
    1  2848  2848  2848 ?           -1 Ssl      0   0:00 sddm
 2848  2854  2854  2854 ?           -1 Ssl      0   0:30  \_ /usr/bin/X :0
-auth /var/run/sddm/:0 -nolisten tcp -background none -noreset vt1
 2848  3193  2848  2848 ?           -1 Sl       0   0:00  \_
/usr/lib/x86_64-linux-gnu/sddm/sddm-helper --socket /tmp/Auth2848.1411307271
--id 1 --start /usr/bin/startkde
 3193  3205  2848  2848 ?           -1 S     1000   0:00      \_ /bin/sh
/usr/bin/startkde
 3205  3256  2848  2848 ?           -1 S     1000   0:00          \_ kwrapper5
ksmserver


2, However, when login on another VT, and use "startx" to launch the KDE, the
input method framework works fine. The corresponding ps tree is:
 1025  2160  2160  1025 tty2      3529 S     1000   0:00  \_ -bash
 2160  3529  3529  1025 tty2      3529 S+    1000   0:00      \_ /bin/sh
/usr/bin/startx
 3529  3546  3529  1025 tty2      3529 S+    1000   0:00          \_ xinit
/etc/X11/xinit/xinitrc -- /etc/X11/xinit/xserverrc :1 -auth
/tmp/serverauth.YmIxtLE0hI
 3546  3547  3547  3547 tty7      3547 Ssl+     0   0:02              \_
/usr/bin/X -nolisten tcp :1 -auth /tmp/serverauth.YmIxtLE0hI
 3546  3555  3555  1025 tty2      3529 S     1000   0:00              \_
/usr/bin/ck-launch-session /usr/bin/dbus-launch --exit-with-session

 3555  3618  3618  3618 ?           -1 Ss    1000   0:00                  \_

 3555  3627  3555  1025 tty2      3529 S     1000   0:00                  \_

\_ kwrapper5 ksmserver

3, seems sddm doesn't do im-launch like startx.

Reproducible: Always

Steps to Reproduce:
1. Power on kubuntu operation system
2. Check input method.
3. Check ps tree.

Actual Results:  
input method cannot be used any more.

Expected Results:  
sddm should launch the im-launch automatically.
