I initially installed VNC4SERVER to run Guacamole (render VM through browser) on an AWS EC2 Linux (Ubuntu 12.04) instance. It worked fine and then I shutdown the instance. After a few days I started it again, and then I noticed VNC not working properly.

I went into terminal and checked it out, and here were the logs:

  GNU nano 2.2.6                               File: /root/.vnc/ip-10-148-67-7:2.log

Can anyone help? Any piece of information or advice would be highly appreciated.

These logs do not give much clue to me. can you try to restart your session see if that works ? –  Raza Jun 4 '13 at 17:53
    
define restart session. I've killed vncserver (vncserver -kill :1 or any number) many times and started it again and again. The logs all say the same thing, the same as above. –  AnimaSola Jun 4 '13 at 17:57
    
Yes, I meant the same. vncserver -kill :1 what error message do you get on the viewer side? can you enable debug log by run the vnc server and viewer with -Log flag like vncserver -Log=*:stderr:100 and vncviwer -Log=*:stderr:100 –  Raza Jun 4 '13 at 18:07
