VNC4Server : sh: /root/.vnc/xstartup: Permission denied

I installed vnc4server ( Xvnc Free Edition 4.1.1 )  on ubuntu 11.04 and connected to that machine from Windows 7 with Ultra VNC viewer.
I got the connection , but window was gray , no GNOME desktop :(

I checked VNC log and found an error “Permission denied”

vncext:      VNC extension running! vncext:      Listening for VNC connections on port 5901 vncext:      created VNC server for screen 0 error opening security policy file /etc/X11/xserver/SecurityPolicy Could not init font path element /usr/X11R6/lib/X11/fonts/Type1/, removing from list!

I linked /root/.vnc/xstartup with /etc/X11/xinit/xinitrc with “ln -s” command.

# ln -s /etc/X11/xinit/xinitrc /root/.vnc/xstartup

lrwxrwxrwx 1 root root   22 2011-07-21 00:10 xstartup -> /etc/X11/xinit/xinitrc

I changed xstartup file’s permission to 755 and after doing that , I could see GNOME desktop :)

# chmod 755 /root/.vnc/xstartup # kill “VNC’s PID” # vncserver

The problem seemed to be caused by file permission.
