Your config for the RollingFileAppender is missing the <file> element. The
manual contains a good example of all the necessary elements [1]. logback
should print a warning in the debug output for this.

It would be helpful if you provided additional details to reproduce the
problem:

 * What version of logback and slf4j are you using?
 * Which flavor (and version) of Linux are you running?
 * Does the same problem occur when you try your logback config in a simple
HelloWorld app (outside of install4j)?

FYI, your logback config works (writes to a file) for me in Android.

It looks like Install4j supports a console [2], when running  the installer
with "-c". It might be worth seeing if logback's debug-output prints in
that console.
