Debian: How to resolve Xserver failure

Question

I keep finding similar posts online but I can't really use the solutions in my case. in my /etc/bash.bashrc file, I have the following code placed at the very bottom:

if [ -e /tmp/.X0-lock ]; then
    rm /tmp/.X0-lock
fi

startx
cd /home/user1/Documents/ProgramFile
./ myProgram.sh

This is to run my program automatically upon startup.

I'm running Debian 6.0.7 squeeze. I want to run my program as root on startup. I executed the following command to disable the GUI:

 update-rc.d -f gdm3 remove

I modified /etc/inittab to allow the root user to automatically login:

1:2345:respawn:/bin/login -f root tty1 </dev/tty1 > /dev/tty1 2>&1

when I boot up my box, I get the following error:

_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

Fatal server error:
Cannot establish any listening sockets - Make sure an X server isn't already running

Please consult the The X.Org Foundation support 
at http://wiki.x.org
for help. 
Please also check the log file at "/var/log/Xorg.0.log" for additional information.

(WW) xf86CloseConsole: KDSETMODE failed: Bad file descriptor   
(WW) xf86CloseConsole: VT_GETMODE failed: Bad file descriptor

Weird thing is this appears in a white box at the top left corner of my screen, it stays there fore a little while (~15 secs) and then I see my code execute and the screen changes to my application.

Q: Can anyone explain to me what is going on here and what I can do to not get the error messages.

Answer 1

Your script doesn't check if X is already running.
Workaround:

if [ -e /tmp/.X0-lock ]; then
   XPID=$(cat /tmp/.X0-lock)
   if ps -p $XPID >/dev/null; then
      echo "X already running"
   else
      rm /tmp/.X0-lock
      startx
   fi
fi

cd /home/user1/Documents/ProgramFile
./myProgram.sh

However I'd do something like this:

# /etc/inittab
3:2345:respawn:/bin/login -f username tty3 < /dev/tty3 > /dev/tty3 2>&1

and

# /home/username/.bashrc
if [ -z "$DISPLAY" ] && [ $(tty) == /dev/tty3 ]; then
  startx -- :0  -quiet -logverbose 11
  cd /mydir
  ./myprog
fi

So you spawn automatically a shell on tty3. Assuming bash is your current shell, bash checks if it runs on tty3, then it executes your stuff.

It looks like you haven't changed your default runlevel and X Server is already running. You should have set it to 3, i.e.:

id:3:initdefault:

Although I don't think your script is going to work anyway. This part:

cd /home/user1/Documents/ProgramFile
./ myProgram.sh

is going to be executed only after X Server stopped.
