How can I enable XIM as input method in Gnome?

[DarDar]

I use Fedora 10 i386 with Gnome desktop environment.
I wanted to redefine some Compose key combinations. So I decided to use xim and local ~/.XCompose file instead of gtk-im-context-simple.
I tried to test how it works and run

GTK_IM_MODULE=xim gedit

from terminal. And here the Compose key were completely ignored. But when I used multipress input method:

GTK_IM_MODULE=multipress gedit

it worked. I pressed the <Compose>,A,A,A... and it cycled like "a", "b", "c", "ä", "2".
I tried viqr input method:

GTK_IM_MODULE=viqr gedit

and it also worked.

Is there any way to enable xim as input method for non-root user?

Solution

After I put these lines into ~/.xinputrc

DISABLE_IMSETTINGS=yes
GTK_IM_MODULE=xim

xim starts working as expected.
