X startup trouble

[Christian Heinze]

Hello everyone,

I have a serious problem getting my X to start. I updated from Warty to 
Hoary, following the instructions of 'GuideToHoary' on the Ubuntu Wiki. 
The first reboot after that update led to the following message:

--- BEGIN ---
'There already appears to be an X server running on display :0.  Should 
I try another display number?  If you answer no, I will attempt to start 
the server on :0 again.  (You can change consoles by pressing Ctrl-Alt 
plus a function key, such as Ctrl-Alt-F7 to go to console 7.  X servers 
usually run on consoles 7 and higher.)'
--- END ---

The only way I could get X to start was to log in over a console. I 
first tried to exec 'startx', then I got the following message:

--- BEGIN ---
Fatal server error:
Server is already active for display 0
         If this server is no longer running, remove /tmp/.X0-lock
         and start again.


When reporting a problem related to a server crash, please send
the full server output, not just the last messages.
Please report problems to debian-x at lists.debian.org.


Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
giving up.
xinit:  unable to connect to X server
xinit:  No such process (errno 3):  Server error.
--- END ---

So I deleted '/tmp/.X0-lock', as the message suggested, and then I could 
start X by 'startx' successfully.

Anyhow, the problem appears over and over after every reboot. Please help!

Best regards,
