Hi, I saw this error message when I accidentally ran startx on tty1 from a screen(1) session.
For some reason, there's a root-owned /dev/tty0 on the machine. Should there be one? I certainly don't seem to see it - I have six VTs set up, and e.g. /dev/tty1 where I'm running that startx is owned by my user. The only non-comment content of Xwrapper.config is "allowed_users=console" man Xwrapper.config fails to run, oddly enough -- 2. That which causes joy or happiness.
