Welcome to LQ!!
Some hints for getting better help:
1. Use thread titles that tell us something about your specific question.
2. Write using whole words, punctuation, etc.
3. Provide all relevant information
In this case, we need to know what version of Linux you are using---eg Ubuntu, Fedora, SUSE, Debian, etc. Also, what exactly were you customizing? And what is working now---and what is not working.
