So I have installed BT3 on my asus eee's ssd harddrive using the tutorial on i-hacked dot com

everything works great initially. then I create a user, logout of root, and login as user. when I type startx I get this error:

xf860OpenConsole: Cannot open/dev/tty0 (Permission denied)

any idea on how to fix this? I don't want to have to be logged in as root all the time. also, when I am logged in as user, and I type su root, password, it says "sorry," and goes back to #.

thanks in advance.
