Very wierd permissions problems.
Recently i've been getting some wierd problems. Firstly I needed to sudo (or su root) to run "halt" or "reboot".
Now, I tried to startx, and it gave me a "you do not have console ownership" error.
"su root" and "startx" worked, as well as "sudo startx"
The thing is I can't think of anything i've done to cause this. The most recent thing i've done is convert my /boot parition to FAT16, but I think my problems started before that.
