Loaded 10.10. Changed usr directory permissions and lost gui. Having to reload. It appears Ubuntu is willing to mess up a machine in order to keep the user from doing so. I mean,,, when you can't use chmod! I've worked a week getting this set up. I'm sure its a security thing as I have no problems doing the same thing on another machine running 8.04. WOW is all I can say,,,, just speechless!
