I'm trying to optimalize my mouse (logitech mx-500) via <a href="http://xorf.com">xorf.com</a> in Ubuntu studio 7.04 (<a href="http://serbiancafe.wordpress.com/2006/07/17/logitech-mx-500-on-ubuntu-606/">http://serbiancafe.wordpress.com/2006/07/17/logitech-mx-500-on-ubuntu-606/ </a>) but when I try to save the changes it says that I do not have root acces I'm also not able to change permissions in the properties of <a href="http://xorf.com">xorf.com</a> does anybody know how to do this? Thanks in advance Best Regards, Koen
