I am asking this question as per the advice given to me to make it more precise and good.
I use Ubuntu 19.04 OS and latest version of LibreOffice. To type Indian languages am using Ibus.
While using Writer, whatever I type in English through Itrans Kannada renders in English only and not in Kannada script. I searched online and tried various routes but am unsuccessful.
I am not a software person but just a common man who is interested in using FOSS. So I am not technically sound but has general information about how to do things like blindly following the instructions:)
Hope some one will feel like helping me
