X doesn't start

[Henny Shafiq]

Linux problem: X won't start. Maybe it's connected with the fact that a few 
days ago I logged in as Henny in X and as root in text, did a few things 
(nothing major) and did  (in text-environment) shutdown -r now. When 
yesterday I wanted to log in X didn't start, the message was: 
can't connect: errno 111 
failed to set default font path 'unix /:-1' 
fatal server error 
could not open default font 'fixed'. 

Can anyone tell me what to do now?
Thanks
Henny
