startx doesn't work

Question

Let's see, I cannot log in in Lubuntu 12.04. On the shell I get when typing startx:

  _XSERVTransSocketUNIXCreateListener: ...SocketCreateListener()  failed
  _XSERVTransMakeA11C0TSServerListeners: server already running

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

 ...
 Please also check the log file at "/var/log/Xorg.0.log" for additional information.  
 ddxSigGiveUp: Closing log
 Server terminated with error (1). CLosing log file

 Invalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyxinit: giving up
 xinit: unable to connect to X server: Resource temporarily unavailable
 xinit: server error  

Before I had only read-right on the file-system with sudo autoremove I got my write-rights back. I removed the .Xauthority* files in /home/username. Still cannot login back

Answer 1

I found a solution for me: Well, I hope someone can use my answer:

I changed my password, reinstalled xserver-xorg by typing: sudo apt-get install --reinstall xorg

After a reboot it worked for me. Notice: I removed the .XAuthority files in /home/username by: sudo rm /home/username/.XAuthority*

to get a shell try Strg-Alt-F1 when you turn on your computer. I actually got my write-rights back by using clear in recovery mode.

Hopefully, this answer can help others as well.

Answer 2

Did you "Make sure an X server isn't already running" by trying something like startx -- :1? Maybe a [g|x|light]dm process was already running and blocking DISPLAY :0.
