I use ibus.
Ed, To work correctly, the rpcalc app also needs to have QT_IM_MODULE=ibus. I don't know what sets it to xim, but whatever sets it to xim is tenacious. I've tried both "im-chooser" and a simple manual change: $ set QT_IM_MODULE=ibus $ export QT_IM_MODULE $ env QT_IM_MODULE QT_IM_MODULE=xim If I create a new user "test" and log on with that userID, the input method defaults to ibus and rpcalc works. So the brute force method to correct my problem might be to totally blow away and recreate my current user account. That would be very destructive. --Doc
