1. Not familiar with this distro, can you log on as user and do 'sudo -i'?
2. There are several ways to accomplish this, without installing any login managers it can be done in ~/.bash_profile.
3. Discover xset command.
This should give you ideas what to search for, using your favorite search engine.
