Sudo gedit/focuswriter does not change input language?

edit

Hi.
I've been struggling to directly save files in my fedora-19-live usb.
The method I found was to "sudo [program]" and work.
However, when I use this method to call, for example gedit, it does not change input language.
The keyboard input on the top bar shows that it changed correctly, byt my typing language Korean does not appear. It remains to be written in English.

This is the result if I do "sudo gedit".

(gedit:2122): Gtk-WARNING *: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

and if I su -> password -> # gedit,

(gedit:2359): dconf-WARNING *: failed to commit changes to dconf: 연결이 닫혔습니다
Error creating proxy: 연결이 닫혔습니다 (g-io-error-quark, 18)
Error creating proxy: 연결이 닫혔습니다 (g-io-error-quark, 18)

Error creating proxy: 연결이 닫혔습니다 (g-io-error-quark, 18)
(gedit:2359): Gtk-CRITICAL **: gtk_application_inhibit: assertion `application->priv->sm_proxy != NULL' failed

"연결이 닫혔습니다" means "connection is closed."

if I do the same process with Focuswriter:

Qt: Session management error: None of the authentication protocols specified are supported

When opening a file, it shoots the "Error creating proxy...".
There are times when it is possible to type in Korean letters, but it is rare, sudden cases. I've tested with other languages, but Russian or Greek seems to work with no problem, and just Korean or some Asian inputs have problems.
Please save me from this problem. I really don't want to end up using MS Windows again. :(
Sorry for my lousy English; it's not my mothertongue.
