This sounds like X is already running. Did you check your other virtual terminals? Assuming you're on tty1, try Alt-F2, Alt-F3, etc. until you find it or run out of F keys. Also, you could try

Code:
ps -ef |grep X
to see if an X process is running. For example, mine gives

Code:
root      1048   788  3 May10 tty7     08:39:35 /usr/lib/xorg/Xorg :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
Which shows that it's running on virtual terminal 7.
