I have install LMDE and then ibus.
However, there is no way I can keep the input method changes that I have made in the preference window of ibus, i.e. I have installed a few input methods/tables and selected a few of those input methods in the preference panel of ibus. After I close the preference panel, and check the preference of ibus again --- all those changes are gone. I tried restarting or totally reinstall ibus and its components but these do not help either.
Whenever, I use an application that has input, such as the simple GEdit or the firefox browser (with the cursor being active at the search box), when I click on the ibus icon, it just says 'No input window'. I changed the preference as described above, and the preference changes are gone.
Please enlighten me, and point me to the solution so that I can use ibus to input in other languages.
Thanks a lot for your help.
