I've done the following but all I get in VNC Viewer is a blank orange screen, any help appreciated.


apt-get -y install ubuntu-desktop tightvncserver
adduser vnc
passwd vnc
echo "vnc ALL=(ALL)       ALL" >> /etc/sudoers
su - vnc
vncpasswd
exit
cd ~
nano .vnc/xstartup


#!/bin/sh

# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
. /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] &amp;&amp; exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] &amp;&amp; xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &amp;
x-terminal-emulator -geometry 1280x1024+10+10 -ls -title "$VNCDESKTOP Desktop" &amp;

#x-window-manager &

save

THEN nano /etc/init.d/vncserver 

THEN paste in the following, then save:

#!/bin/sh -e
### BEGIN INIT INFO
# Provides:          vncserver
# Required-Start:    networking
# Default-Start:     3 4 5
# Default-Stop:      0 6
### END INIT INFO

PATH="$PATH:/usr/bin/"

# The Username:Group that will run VNC
export USER="vnc"
#${RUNAS}

# The display that VNC will use
DISPLAY="1"

# Color depth (between 8 and 32)
DEPTH="16"

# The Desktop geometry to use.
#GEOMETRY="x"
#GEOMETRY="800x600"
GEOMETRY="1024x768"
#GEOMETRY="1280x1024"

# The name that the VNC Desktop will have.
NAME="my-vnc-server"

OPTIONS="-name ${NAME} -depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}"

. /lib/lsb/init-functions

case "$1" in
start)
log_action_begin_msg "Starting vncserver for user '${USER}' on   localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"
;;

stop)
log_action_begin_msg "Stopping vncserver for user '${USER}' on localhost:${DISPLAY}"
su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}"
;;

restart)
$0 stop
$0 start
;;
esac

exit 0


Then ctrl-x to save, Y for Yes, and enter to accept file name.

THEN

chown -R vnc. /home/vnc/.vnc &amp;&amp; chmod +x /home/vnc/.vnc/xstartup
sed -i 's/allowed_users.*/allowed_users=anybody/g' /etc/X11/Xwrapper.config

THEN

chmod +x /etc/init.d/vncserver &amp;&amp; service vncserver start

THEN

update-rc.d vncserver defaults

THEN

reboot.

FINALLY: go in there with tightvnc viewer client, and voila, blank kool aid tangerine orange screen.

any help appreciated, of course it's been 3 x 8 hour evenings so far :}


Question: Can excited electrons fall back to their ground state without the emission of photons?
Answer: You are wanting to know about the Auger process.  The answer is yes.  An excited electron can emit a photon when it falls to a lower orbital, or it can give its energy to another electron in the atom and eject it instead.  The chances of this occurring are dependent on which atom, which energy transition, and to a very small extent the chemical environment.
