I have installed Linux and it works just fine, if I log in as root. When I log in as a 'normal' user a lot of thing don't work. For example I can't use the pon command when I am not the root. I also can't start X11 when I am not the root. The system tells me I have to be a root for this. I think this is not a good security situation. How can I change this? TIA, Robert-Jan Kuijvenhoven
